java继承与覆写小练习

最近学习java到了继承的部分，写个小程序用以巩固。

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");
}

}
