子类

public class Michael extends Mouse{

  private int IQ;
  public Michael(int id,int age,int IQ){
   super(id,age);
   this.IQ=IQ;

  }

public String toString(){
System.out.print(age+","+id+","+IQ);
return age+""+id+""+IQ;

}
public static void main(String[] agrs ){
  Mouse mic= new Michael(454,4545,454);
  mic.toString();
 }
}

父类


public class Mouse{
 protected int id;
 protected int age;
 public Mouse(int id,int age){
   this.id=id;
   this.age=age;
  }
  public String toString(){



     return id+""+age;

   }
 /* 
继承 不能重写 final 和静态变量
 public static void main(String[] agrs){


    Mouse mouse = new Mouse(123,12);
    mouse.toString();
  }*/

}
