Java构造方法 super 及自定义异常throw合集详解用法

public class Zi extends fu{

    public int message=35;



public Zi(){

    System.out.println("我是谁");
}}

 public void show(int message)
    {
        System.out.println(this.message);//返回本类的成员变量
        System.out.println(super.message);//返回父类的成员变量
    }

 public Zi(int name){

System.out.println(name);


    }

public fu(int name){

        System.out.println(name);
    }

 Zi sw=new Zi(200);   //    带参的：访问带参的子类带参构造方法

 public Zi(int name){

super(name);      //加这个
System.out.println(name);


    }

public class Student {




    public void sctrr(int score) throws uytig{
if(score<0||score>100){
        throw new uytig(); //throw  异常对象



    }
else {
    System.out.println("方法异常！");

}}}

public class uytig extends Exception{


    public  uytig(){
        super();

    }

public  uytig(String message){
    super();

// public Exception(String message) {
//        super(message);
//    }
    // public Throwable(String message) {
    //        fillInStackTrace();
    //        detailMessage = message;
    //    }
}

public class fu {


    public static void main(String[] args) throws uytig{


        Student sc=new Student();


        try {
            sc.sctrr(98);
        } catch (uytig uytig) {
            uytig.printStackTrace();
        }


    }
}
