Solution in JAVA (judge verdict: Wrong Answer)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	public static void main(String[] args) {
		 try {
		 BufferedReader buf = new BufferedReader(new InputStreamReader(System.in));
		
		 String ln;
		ln = buf.readLine();
		
       String[] strAry = ln.split(" ");
       int x = Integer.parseInt(strAry[0]);
       int y = Integer.parseInt(strAry[1]);
		
       System.out.println(x*2 +" " + (y*2+x*2));
			} catch (IOException e) {
				// TODO ????????????????????? catch ????????????
				e.printStackTrace();
