		this.id=id;
		this.income=income;
	}
	public void Work() {
		System.out.println(this.name);

	}
	public String getName() {
		return name;
	}


	public void setName(String name) {
		this.name = name;
	}


	public int getId() {
		return id;
	}


	public void setId(int id) {
		this.id = id;
	}


	public int getIncome() {
		return income;
	}


	public void setIncome(int income) {
		this.income = income;
	}


	
}
//

	this.name=name;
	this.id=id;
	this.income=income;
	this.bonus=bonus;
}


public int getBonus() {
	return bonus;
}

	System.out.println(this.bonus);
}
}
//

	}

}

需求二：

public class Teach {
public String name;
public int age;
public Teach() {

}
public void XingWei() {
	System.out.println(this.name+"需要吃饭");
}
public void Pross() {
	System.out.println(this.name+"上课");
}
public String getName() {
	return name;
}
public void setName(String name) {
	this.name = name;
}
public int getAge() {
	return age;
}
public void setAge(int age) {
	this.age = age;
}

}
//
public class Stud extends Teach{
	public Stud() {
		
	}
  public  Stud(String name, int age) {
		this.name=name;
		this.age=age;		
		}
	public void Pross() {
		System.out.println(this.name+"听课");
	}
	

}
//
public class T1 {
	public static void main(String[] args) {
		Pro r=new Pro("李四",121121,10000);
		r.Work();
		Jingli s=new Jingli("张三",120120,20000,5000);
		s.Work();
		Teach r1=new Teach("张老师",30);
		r1.XingWei();
		r1.Pross();
		Stud s1=new Stud("王同学",20);
		s1.XingWei();
		s1.Pross();
	}

}

需求三：

public class Cat {
	public String name;
	public char fur;
	public int leg;
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public char getFur() {
		return fur;
	}

	public void setFur(char fur) {
		this.fur = fur;
	}

	public int getLeg() {
		return leg;
	}

	public void setLeg(int leg) {
		this.leg = leg;
	}

	public Cat() {
		
	}

	public  Cat(String name,char fur,int leg) {
		this.name=name;
		this.fur=fur;
		this.leg=leg;
	}
	public void XingWei() {
		System.out.println(this.name+"需要吃饭");
	}
	public void Catchmouse() {
		System.out.println(this.name+"在夜里抓老鼠");
	}
}
//
public class Dog extends Cat {
