如果调用的代码有异常抛出，那需要try…catch处理或者抛异常

package com.exception.test;

import java.util.Scanner;

public class Throws {
    public static void main(String[] args) {
        Calculate cal=new Calculate();
        try {
            cal.remainder();
        } catch (Exception e) {
            e.printStackTrace();
        }

        System.out.println("程序继续执行");

    }
}
class Calculate{
    void remainder() throws Exception{
        int a,b,c;
        Scanner sc=new Scanner(System.in);
        a=sc.nextInt();
        b=sc.nextInt();
        c=a%b;
        System.out.println("余数为："+c);

    }
}

结果：
