异常03自定义异常及经验小结

package com.exception.demo02;

//自定义异常类
public class MyException extends Exception{

    //传递数字>10;
    private int detail;

    public MyException(int a) {
        this.detail = a;
    }

    //toString:异常的打印信息
    @Override
    public String toString() {
        return "MyException{" +
                "detail=" + detail +
                '}';
    }

package com.exception.demo02;

public class Text {

    //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) {
            //增加了一些处理异常的代码
            System.out.println("MyException=>"+e);
        }
    }
}
