javapackage com.example;

public class Father { private int age; public String name;

public void work() { System.out.println(Working...); }

public void drive() { System.out.println(Driving...); }}

public class Son extends Father { protected int age;

public Son(int age, String name) { this.age=age; this.name=name; }

@Override public void work() { System.out.println(Son is working...); }

@Override public void drive() { System.out.println(Son is driving...); }}

包a中编写一个类Father，具有属性：年龄（私有）、姓名（公有）；具有功能：工作（公有）、开车（公有）。在包a中编写一个子类Son，具有属性：年龄（受保护的）、姓名；具有功能：玩（私有）、学习（公有）。最后在包b中编写主类Test，在主类的main方法中测试类Father与类Son。

package a; public class Father { private int age; public String name; private void play(){ System.out.println("兴趣"); } public void Study(){ System.out.println("学习"); } } package b; import a.Father; public class Son extends Father{ protected int age; public String name; private void play(){ System.out.println("游戏"); } public void Study(){ System.out.println("韩语"); } } import a.Father; public class test { public static void main(String[] args) { Father t=new Father(); Son c=new Son(); //t.play();私有 t.Study(); //c.play();私有 c.Study(); } }
