Day16自定义异常

package com.exception.demo02;
//自定义的异常类
public class MyException extends Exception{
    //传递数字>10抛出异常
    private  int data1;

    public MyException(int a) {
        this.data1=a;
    }
    //toString:异常的打印信息

    @Override
    public String toString() {
        return "MyException{" + "data1=" + data1 + '}';
    }
}

package com.exception.demo02;

public class Test {
    //可能会存在异常的方法
    static void test(int a) throws MyException{
        System.out.println("传递的参数为："+a);
        if(a>10){
            throw new MyException(a);//抛出
        }
        System.out.println("ok");
    }

    public static void main(String[] args) {
        try {
            test(11);
        } catch (MyException e) {
            //增加一些处理异常的代码
            System.out.println("MyException=>"+e);
        }
    }
}
