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){
         System.out.println(a+b+" "+(a-b)+" "+a*b+" "+a/b+" "+a%b);
    }else if(a<b){
        System.out.println(a+b+" "+(b-a)+" "+a*b+" "+b/a+" "+b%a);
    }
    
}

}

键盘扫描器接受我们要的的两个数字,用if语句来判断如果a>b,会怎样然后输出,else if a<b,会输出哪些.
