Java中關於繼承和覆寫的實例分享

最近學習java到了繼承的部分，寫個小程式用以鞏固。

import java.util.Scanner;//导入输入包
public class testfather {
public static void main(String[] args) {
// TODO Auto-generated method stub
   Scanner test = new Scanner(System.in);
   System.out.println("请输入姓名：");
   String newName = test.nextLine();
   System.out.println("请输入年龄：");
   int newAge = test.nextInt();
   fatherTest a = new fatherTest(newName, newAge);
   sonTest b= new sonTest(newName,newAge,100);
a.talk();
b.talk();
}
}
class fatherTest {
private String name;
private int age;
fatherTest(String name, int age) {
this.name = name;
this.age = age;
}
public int getAge() 
{
return this.age;
}
public String getName()
{
return this.name;
}

public void talk()
{
System.out.println("父类："+"我叫"+getName()+","+"今年"+getAge()+"岁了。");
}
}
class sonTest extends fatherTest
{   

private int money;
public sonTest(String name,int age,int money)
{   
super(name, age);//继承
this.money = money;
}
private int getMoney()
{
return this.money;
}
public void talk()//覆写，与父类方法同名
{
System.out.println("子类："+"我叫"+getName()+","+"今年"+getAge()+"岁了。"+"我有"+getMoney()+"元");
}

}
