Every class containing abstract method must be declared abstract. .
An abstract method is only declared, not implemented.
仅声明抽象方法但未实现。This means that an abstract class does not necessarily have an abstract method.
也就是说抽象类不一定必须含有抽象方法。The method declared but not implemented is called an abstract method.
一个被声明为abstract而没有实现的方法称为抽象方法。F() invocation because it references an abstract method.
F()导致了编译时错误，原因是它引用了抽象方法。Modular programming Protocol(object-oriented programming) Abstract method.
模块化编程协议（面向对象程序设计）抽象方法.An abstract method is declared with the abstract modifier and is permitted only in a class that is also declared abstract. .
抽象方法使用abstract修饰符进行声明，并且只允许出现在同样被声明为abstract的类中。Although an abstract method is implicitly also a virtual method, it cannot have the modifier virtual.
虽然抽象方法同时隐含为虚方法，但是它不能有virtual修饰符。Because an abstract method declaration provides no actual implementation, there is no method body;
因为抽象方法声明不提供实际的实现，所以没有方法体；.Because an abstract method provides no actual implementation, the method-body of an abstract method simply consists of a semicolon.
由于抽象方法不提供任何实际实现，因此抽象方法的method-body只由一个分号组成。If a class has atleast one abstract method, then, the class must be declared as abstract otherwise it will give compile time error.
如果一个类包含抽象方法，那么该类一定要声明为抽象类，否则将出现编译错误。If there is any abstract method in a class, that class must be abstract. .
如果一个类中有抽象方法，那么这个类必须是抽象类。Java provides a mechanism for doing this called the abstract method.
针对这个问题，Java专门提供了一种机制，名为“抽象方法”。Any class inheriting the current class must either override the abstract method or declare itself as abstract. .
任何从abstract类继承而来的类都要实现基类的abstract方法，或者声明自身为abstract类。For example, if the abstract method is defined as protected, the function implementation must be defined as either protected or public, but not private.
例如某个抽象方法被声明为受保护的，那么子类中实现的方法就应该声明为受保护的或者公有的，而不能定义为私有的。Abstract classes and abstract methods.
