Solution in JAVA (judge verdict: Wrong Answer)

import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

class Main
{

	public static void main(String[] args)
	{
		Scanner scanner = new Scanner(System.in);
		ArrayList<Integer> lstInt = new ArrayList<Integer>();

		for (; scanner.hasNext();)
		{
			lstInt.add(scanner.nextInt());
			if (lstInt.size() == 10)
				break;
		}

		Collections.sort(lstInt);

		for (int i = 0; i < 3; ++i)
			System.out.println(lstInt.get(i));

		scanner.close();
	}
