Solution in JAVA (judge verdict: Accepted)

import java.util.*;

public class Main {
    
    public static void main(String arg[]) {
        try{
            Scanner scan = new Scanner(System.in);
            int a = scan.nextInt();
            int b = scan.nextInt();
            if(0<a && a<101 && 0<b && b<101){
            int x = a*b;
            int y = (a + b)*2;
            System.out.println(x+" "+y);
            }else{
                System.out.println("1??????100?????§???????????§???");
            }
            
        }catch(InputMismatchException ex){
            System.out.println("1??????100?????§????????¶??°?????\?????????????????????");
        }
    }
