Answer 1

import java.util.Random;

public static void main(String[] args)
{

    int a = 1 + (int)(Math.random()*99);
    int guess = 0;
    int count = 0;

    while(guess != a)
    {
        guess = Integer.parseInt(JOptionPane.showInputDialog("Enter a Number"));
        count++;
        if (guess > a)
        {
         JOptionPane.showMessageDialog(null,"lower!");
        }
       else if (guess < a)
        {
         JOptionPane.showMessageDialog(null,"higher!");
        }
    }
         JOptionPane.showMessageDialog(null,"Congratulations. You guessed the number with " +count+ " tries");
    }

}
