求助大神如何用Java写出这两个题目的代码？

第一题
package baidu;

public class Student {
protected String name;
protected int age;

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

public void show(){
System.out.println("name = " + name);
System.out.println("age = " + age);
}
}
---------------------------------
package baidu;

public class Undergraduate extends Student {
private String degree;

public Undergraduate(String name, int age, String degree) {
super(name, age);
this.degree = degree;
}

public void show(){
System.out.println("name = " + name);
System.out.println("age = " + age);
System.out.println("degree = " + degree);
}
}

------------------------
package baidu;

public class TestRun {
public static void main(String[] args) {
Student s = new Student("singi",12);
s.show();
Undergraduate ug = new Undergraduate("lily",23,"本科");
ug.show();
}
}

输出:
name = singi
age = 12
name = lily
age = 23
degree = 本科
第二题:
package baidu;

public class Man {
String name;

public Man(String name) {
this.name = name;
}

public void business(){
System.out.println("在方法内输出谈生意");
}
}

----------------
package baidu;

public class SuperMan extends Man {
String name;

public SuperMan(String name, String name1) {
super(name);
this.name = name1;
}

@Override
public void business() {
System.out.println("在方法内输出谈几个亿的大单子");
}

public void fly(){
System.out.println("在方法内输出超人不会飞");
}
}

------------------
package baidu;

public class TestMan {
public static void main(String[] args) {
Man m = new Man("singi");
System.out.println(m.name);
m.business();
SuperMan sm = new SuperMan("lily","xiaoming");
System.out.println(sm.name);
sm.business();
sm.fly();
}
}

输出:
singi
在方法内输出谈生意
xiaoming
在方法内输出谈几个亿的大单子
在方法内输出超人不会飞
