import java.util.Scanner;
    public class Main {
        public static void main(String[] args) {
            Scanner scanner = new Scanner(System.in);
            int a = scanner.nextInt();
            int b = scanner.nextInt();
            scanner.close();

            //write your code here......
            if(a<b){
            int temp = a;
            a = b;
            b = temp;
            }
            System.out.printf("%s %s %s %s %s",a+b,a-b,a*b,a/b,a%b);
        }
    }

比较a与b

如果a小于b，a与b 交换位置即可。
