2023.8.1 周二：自定义异常

//MyException
//继承Exception的类，即为 自定义的异常类
public class MyException extends Exception{
    //传递数字>10，则报异常
    private int detail;
   //Alt+Insert 自动添加构造方法
    public MyException(int a) {
        this.detail = a;
    }
    //toString:异常的打印信息  快捷键：Alt+Insert ：toString
    @Override
    public String toString() {
        return "MyException{" +
                "detail=" + detail +
                '}';
    }

}

//test
public class Test {
    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) {
                System.out.println("MyException->"+e);
            }
        }

    }
