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）。
