课后作业二

没整明白怎么提交到码云上
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        System.out.println("请任意输入2个数字");
        Scanner input = new Scanner(System.in);
        int num1 = input.nextInt();
        int num2 = input.nextInt();
        System.out.println("请输入+，-，*，/其中一种关系运算符");
        char c = input.next().charAt(0);
        switch (c) {
            case '+':
                System.out.println(num1 + "+" + num2 + "=" + (num1 + num2));
                break;
            case '-':
                System.out.println(num1 + "-" + num2 + "=" + (num1 - num2));
                break;
            case '*':
                System.out.println(num1 + "*" + num2 + "=" + (num1 * num2));
                break;
            case '/':
                System.out.println(num1 + "/" + num2 + "=" + (num1 / num2));
                break;
            default:
                System.out.println("非法运算符");
                break;
        }
    }
