java基础之 Advanced Class DesignAbstract ClassesIn many programming situations, you want to specify an abstraction without specifyingimplementation-level details. In such cases, you can use either abstract classes or interfaces. Abstract classesare used when you want to define an abstraction with some common functionality.Points to RememberReview the following points about abstract classes and abstract methods :• The abstract keyword can be applied to a class or a non-static method.• An abstract class may have methods or fields declared static. However, the abstractkeyword cannot be applied to fields or static methods.• An abstract class can extend another abstract class or can implement an interface.• An abstract class can be derived from a concrete class! Although the language allowsit, it is not a good idea to do so.• An abstract class need not declare an abstract method, which means it is notnecessary for an abstract class to have any methods declared as abstract. However, ifa class has an abstract method, it should be declared as an abstract class.• A subclass of an abstract class needs to provide implementation of all the abstractmethods; otherwise you need to declare that subclass as an abstract class.Using the “final” KeywordThe final keyword can be applied for classes, methods, and variables. You cannot extend a final class,you cannot override a final method, and you cannot change the value of a final variable once it is initialized.Final ClassesA final class is a non-inheritable class—that is to say, if you declare a class as final, you cannot subclass it.Two important reasons you may not want to allow a class to be subclassed are:1. To prevent a behavior change by subclassing. In some cases, you may think thatthe implementation of the class is complete and should not change. If overridingis allowed, then the behavior of methods might be changed. You know that aderived object can be used where a base class object is required, and you maynot prefer it in some cases. By making a class final, the users of the class areassured the unchanged behavior.2. Improved performance. All method calls of a final class can be resolved atcompile time itself. As there is no possibility of overriding the methods, it is notnecessary to resolve the actual call at runtime for final classes, which translates toimproved performance. For the same reason, final classes encourage the inliningof methods. With inlining, a method body can be expanded as part of the callingcode itself, thereby avoiding the overhead of making a function call. If the callsare to be resolved at runtime, they cannot be inlined.In the Java library, many classes are declared as final; for example, the String (java.lang.String)and System (java.lang.System) classes. These classes are used extensively in Java programs. If thesetwo classes are not declared final, it is possible for someone to change the behavior of these classes bysubclassing and then the whole program can start behaving differently. To avoid such a problem, widelyused classes like these and wrapper classes such as Number and Integer are made final in the Java library.Final Methods and VariablesIn a class, you may declare a method final. The final method cannot be overridden. Therefore, if you havedeclared a method as final in a non-final class, then you can extend the class but you cannot override thefinal method. However, other non-final methods in the base class can be overridden in the derived classimplementation.Final variables are like CD-ROMs: once you write something on them, you cannot write again. Inprogramming, constants such as PI can be declared as final since you don’t want anyone to modify theirvalues. If you try to change a final variable after initialization, you will get a compiler error.Points to RememberReview the following points :• The final modifier can be applied to a class, method, or variable. All methods of afinal class are implicitly final (hence non-overridable).• A final variable can be assigned only once. If a variable declaration defines avariable as final but did not initialize it, then it is referred to as blank final. You needto initialize a blank final in all the constructors you have defined in the class or in aninitialization block.• The keyword final can be applied to parameters. The value of a final parametercannot be changed once assigned.Flavors of Nested ClassesCreate inner classes including static inner class, local class, nested class, and anonymous inner classClasses defined within the body of another class (or interface) are known as nested classes. Typicallyyou define a class, which is a top-level class directly belonging to a package. In contrast, nested classes areclasses contained within another class or interface.What is the benefit of creating classes inside another class or interface? There are several benefits. First,you can put related classes together as a single logical group. Second, nested classes can access all classmembers of the enclosing class, which might be useful in certain cases. Third, nested classes simplify code.For example, anonymous inner classes are useful for writing simpler event-handling code with AWT/Swing.There are four types or flavors of nested classes in Java:• Static nested class• Inner class• Local inner class• Anonymous inner classThe distinctions among these four flavors are not evident at first sight. Figure 3-1 helps clarify thedifferences between them. A local class is defined within a code block (whether a method, constructor, orinitialization block), whereas a non-local class is defined inside a class. A static class is qualified using thestatic keyword, whereas a non-static class does not use the static keyword with the class definition. In ananonymous class, you don’t provide the name of the class; you just define its body.As you can observe in Figure 3-1, static nested classes are static and non-local, whereas inner classesare non-static and non-local. A non-static and local nested class is a local inner class, and a local andanonymous nested class is an anonymous inner class.Static Nested Classes (or Interfaces)You can define a class (or an interface) as a static member inside another class (or interface). Since theouter type can be a class or an interface and the inner ones can also be a class or interface, there are fourcombinations. The following are examples of these four types so that you can see their syntax:class Outer { // an outer class has a static nested classstatic class Inner {}}interface Outer { // an outer interface has a static nested classstatic class Inner {}}class Outer { // an outer class has a static nested interfacestatic interface Inner {}}interface Outer { // an outer interface has a static nested interfacestatic interface Inner {}}You don’t have to explicitly use the static keyword with a nested interface, since it is implicitly static.Now, let’s look at an example that creates and uses static nested classes.Points to RememberHere are some notable aspects of static nested classes (and interfaces) that will help you on the OCPJP 8 exam:• The accessibility (public, protected, etc.) of the static nested class is defined bythe outer class.• The name of the static nested class is expressed withOuterClassName.NestedClassName syntax.• When you define an inner nested class (or interface) inside an interface, the nestedclass is declared implicitly public and static. This point is easy to remember: anyfield in an interface is implicitly declared public and static, and static nestedclasses have this same behavior.• Static nested classes can be declared abstract or final.• Static nested classes can extend another class or they can be used as base classes.• Static nested classes can have static members. (As you’ll see shortly, this statementdoes not apply to other kinds of nested classes.)• Static nested classes can access the members of the outer class (only static members,obviously).• The outer class can also access the members (even private members) of the nestedclass through an object of a nested class. If you don’t declare an instance of thenested class, the outer class cannot access nested class elements directly.Inner ClassesYou can define a class (or an interface) as a non-static member inside another class. How about declaring aclass or an interface inside an interface? As you just saw in the third bullet above about static inner classes,when you define a class or an interface inside an interface, it is implicitly static. So, it is not possible todeclare a non-static inner interface! That leaves two possibilities:class Outer { // an outer class has an inner classclass Inner {}}class Outer { // an outer class has an inner interfaceinterface Inner {}}Every inner class is associated with an instance of the outer class. in other words, an inner class is alwaysassociated with an enclosing object.The outer and inner classes share a special relationship, like friends or members of same family.Member accesses are valid irrespective of the access specifiers such as private. However, there is subtledifference. You can access members of an outer class within an inner class without creating an instance; butthis is not the case with an outer class. You need to create an instance of inner class in order to access themembers (any members, including private members) of the inner class.One limitation of inner classes is that you cannot declare static members in an inner class, like this:class Outer {class Inner {static int i = 10;}}If you try to do so, you’ll get the following compiler error:Outer.java:3: inner classes cannot have static declarationsstatic int i = 10;Points to RememberHere are some important rules about inner classes and interfaces that might prove useful in the OCPJP 8 exam:• The accessibility (public, protected, etc.) of the inner class is defined by theouter class.• Just like top-level classes, an inner class can extend a class or can implementinterfaces. Similarly, other classes can extend an inner class, and other classes orinterfaces can extend or implement an inner interface.• An inner class can be declared final or abstract.• Inner classes can have inner classes, but you’ll have a hard time reading orunderstanding such complex nesting of classes. (Meaning: Avoid them!)Local Inner ClassesA local inner class is defined in a code block (say, in a method, constructor, or initialization block). Unlikestatic nested classes and inner classes, local inner classes are not members of an outer class; they are justlocal to the method or code in which they are defined.Here is an example of the general syntax of a local class:class SomeClass {void someFunction() {class Local { }}}As you can see in this code, Local is a class defined within someFunction. It is not available outside ofsomeFunction, not even to the members of the SomeClass. Since you cannot declare a local variable static,you also cannot declare a local class static.Since you cannot define methods in interfaces, you cannot have local classes or interfaces inside aninterface. Nor can you create local interfaces. In other words, you cannot define interfaces inside methods,constructors, and initialization blocks.You can pass only final variables to a local inner class. if you don't declare a variable that a local innerclass accesses, the compiler will treat it as effectively final.Points to RememberThe following points about local classes may come up in the OCPJP 8 exam:• You can create a non-static local class inside a body of code. Interfaces cannot havelocal classes, and you cannot create local interfaces.• Local classes are accessible only from the body of the code in which the class isdefined. The local classes are completely inaccessible outside the body of the code inwhich the class is defined.• You can extend a class or implement interfaces while defining a local class.• A local class can access all the variables available in the body of the code in which itis defined. Variables accessed by local inner classes are considered effectively final.Anonymous Inner ClassesAs the name implies, an anonymous inner class does not have a name. The declaration of the class automaticallyderives from the instance-creation expression. They are also referred to simply as anonymous classes.An anonymous class is useful in almost all situations where you can use a local inner class. A localinner class has a name, whereas an anonymous inner class does not—and that’s the main difference. Anadditional difference is that an anonymous inner class cannot have any explicit constructors. A constructoris named after the name of the class, and since an anonymous class has no name, it follows that you cannotdefine a constructor!(A note here before we proceed: there are no such things as “anonymous interfaces.”)Here is an example to understand the syntax of a local class:class SomeClass {void someFunction() {new Object() { };}}This code looks cryptic, doesn’t it? What is going on here? In the statement new Object() { };, you aredeclaring a derived class of Object directly using the new keyword. It doesn’t define any code and returns aninstance of that derived object. The created object is not used anywhere, so it is ignored. The new expressioninvokes the default constructor here; you could choose to invoke a multiple argument constructor of thebase class by passing arguments in the new expression.Points to RememberNote these points about anonymous classes that may be useful for the OPCJP 8 exam:• Anonymous classes are defined in the new expression itself.• You cannot explicitly extend a class or explicitly implement interfaces when definingan anonymous class.Enum Data TypeUse enumerated types including methods, and constructors in an enum typePoints to Remember• Enums are implicitly declared public, static, and final, which means you cannotextend them.• When you define an enumeration, it implicitly inherits from java.lang.Enum.Internally, enumerations are converted to classes. Further, enumeration constantsare instances of the enumeration class for which the constant is declared as amember.• You can apply the valueOf() and name() methods to the enum element to return thename of the enum element.• If you declare an enum within a class, then it is by default static.• You cannot use the new operator on enum data types, even inside the enum class.• You can compare two enumerations for equality using == operator.• If enumeration constants are from two different enumerations, the equals() methoddoes not return true.• When an enumeration constant’s toString() method is invoked, it prints the nameof the enumeration constant.• The static values() method in the Enum class returns an array of the enumerationconstants when called on an enumeration type.• Enumeration constants cannot be cloned. An attempt to do so will result in aCloneNotSupportedException.Enum avoids magic numbers, which improves readability and understandability of the source code. also,enums are typesafe constructs. therefore, use enums wherever you need a set of related constants.InterfacesDevelop code that declares, implements, and/or extends interfaces and use the atOverride annotationAn interface is a set of abstract methods that defines a protocol (i.e., a contract for conduct). Classesthat implement an interface must implement the methods specified in the interface. An interface defines aprotocol, and a class implementing the interface honors the protocol. In other words, an interface promisescertain functionality to its clients by defining an abstraction. All the classes implementing the interfaceprovide their own implementations for the promised functionality.Points to RememberHere are some key points about interfaces that will help you in the OCPJP 8 exam:• An interface cannot be instantiated. A reference to an interface can refer to an objectof any of its derived types implementing it.• An interface can extend another interface. Use the extends (and not the implements)keyword for extending another interface.• Interfaces cannot contain instance variables. If you declare a data member in aninterface, it should be initialized, and all such data members are implicitly treated as“public static final” members.• An interface can have three kinds of methods: abstract methods, default methods,and static methods.• An interface can be declared with empty body (i.e., an interface without anymembers). For example, java.util defines the interface EventListenerwithout a body.• An interface can be declared within another interface or class; such interfaces areknown as nested interfaces.• Unlike top-level interfaces that can have only public or default access, a nestedinterface can be declared public, protected, or private.• If you are implementing an interface in an abstract class, the abstract class does notneed to define the method. But, ultimately a concrete class has to define the abstractmethod declared in the interface.• You can use the @Override annotation for a method to indicate that it is overriding amethod from its base type(s).Points to RememberHere are some key points about abstract, default, and static methods that will help you in the OCPJP 8 exam:• You cannot declare members as protected or private. Only public access isallowed for members of an interface. Since all methods are public by default, you canomit the public keyword.• All methods declared in an interface (i.e., without a method body) are implicitlyconsidered to be abstract. If you want, you can explicitly use the abstract qualifierfor the method.• Default methods must have a method body. Default methods must be qualifiedusing the default keyword. The classes implementing the interface inherit thedefault method definitions and they can be overridden.• A default method can be overridden in a derived class as an abstract method; forsuch overriding, the @Override annotation can also be used.• You cannot qualify default methods as synchronized or final.• Static methods must have a method body and they are qualified using the statickeyword.• You cannot provide abstract keyword for static methods: Remember that youcannot override static methods in derived classes, so it’s conceptually not possible toleave static methods abstract by not providing a method body.• You cannot use default keyword for static methods because all default methods areinstance methods.Lambda Functionsintroduction of lambdas required coordinated changes in the language, library, and the vMimplementation:• the arrow operator (“->”) for defining lambda functions, the double colon operator(“::”) used for method references, and the default keyword• the streams library and the integration of the collections library with streams• lambda functions are implemented using the invokedynamic instruction introducedin Java 7to support introduction of lambdas into the language, the type inference has also been strengthened inJava 8. lambdas enabled library writers to create parallel algorithms in the library to exploit inherentparallelism in the modern hardware (i.e., multi cores).Lambda Functions: SyntaxA lambda function consistss of optional parameters, the arrow token, and the body:LambdaParameters -> LambdaBody• LambdaParameters are parameters to the lambda function are passed within openingparenthesis “(“ and closing parenthesis ”)”. When more than one parameter ispassed, they are separated by commas.• The arrow operator. To support lambdas, Java has introduced a new operator “->”,also known as lambda operator or arrow operator. This arrow operator is requiredbecause we need to syntactically separate the parameter from the body.• LambdaBody can be an expression or a block. The body could consist of singlestatement (in that case no explicit curly braces defining a block are required); sucha lambda body is known as "expression lambda." If there are many statements in alambda body, they need to be in a block of code; such a lambda body is known as“block lambda.”Compiler performs type inference for lambda expressions:• The compiler infers the type of the parameters if you do not specify the typeparameters in a lambda function definition. When you specify the type ofparameters, you need to specify all or none; or else you will get a compiler error.• You can omit the parenthesis if there is only one parameter. But in this case, youcannot provide the type explicitly. You should leave it to the compiler to infer thetype of that single parameter.• The return type of the lambda function is inferred from the body. If any of the code inthe lambda returns a value, then all the paths should return a value; or else you willget a compiler error.Some examples of valid lambda expressions (assuming that relevant functional interfaces are available):• (int x) -> x + x• x -> x % x• () -> 7• (int arg1, int arg2) -> (arg1 + arg2) / (arg1 – arg2)Effectively Final VariablesLambda functions can refer to local variables from the enclosing scope. The variable needs to be explicitlydeclared final or that variable will be treated as effectively final. Effectively final means that the compiler treatsthe variable as a final variable and will issue an error if we try to modify it within the lambda function or in therest of the function. This behavior of lambdas is similar to accessing variables in outer scope from local andanonymous classes. The variables they access are also considered effectively final 博狗亚洲官方百家_乐夫人听到那人说话
