Answer 1

import java.util.Arrays;
import java.util.Scanner;


public class App {


	/**
	 * The start point of the program
	 * 
	 * @param args
	 * 
	 */
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		int numbers[] = new int[15];
		for (int i = 0; i < 15; i++) {
			System.out.print("Enter the number " + (i + 1) + ": ");
			numbers[i] = keyBoard.nextInt();
		}
		Arrays.sort(numbers);
		int counter = 0;
		System.out.println("\nAll two digits number in ascending order");
		for (int i = 0; i < 15; i++) {
			if (numbers[i] >= 10 && numbers[i] < 100) {
				System.out.print(numbers[i] + " ");
				counter++;
			}
		}
		System.out.println("\nThe number of two digits values: " + counter);
		keyBoard.close();
	}
