How do I clear the screen?
 
How do I clear the screen when I restart the "game" with a loop?
:
import cs1.Keyboard;
import java.util.*;

public class HiLo
{
    public static void main (String[] args)
    {
        int play = 1;
        while(play > 0)
        {
        Random generator = new Random();
        int answer = generator.nextInt(100)+1;
       
        System.out.println("The computer is thinking of a number \nbetween 1 and 100. What is it?");
        int escape = 0;
        while(escape < 1)
        {
        int guess = Keyboard.readInt();
       
        if(guess == answer)
        {
            System.out.println("That's it");
            escape = 1;
        }
        else if(guess > answer)
        {
            System.out.println("Too High");
        }
        else if(guess < answer)
        {
            System.out.println("Too Low");
        }
        }
       
        System.out.println("Would you like to play again (y/n)");
        char again = Keyboard.readChar();
        if(again == 'y')
        {
            play = 1;
        }
        else if(again == 'n')
        {
            play--;
        }
    }
     
    }
}

Could try the escape code for clearing the screen

:
System.out.print ("\033c");

Your mileage may vary.

where you want to clear the screen :)

if the code doesn't work, you can also print 30 newlines, that will also clear the screen.

The code I gave you is an standard terminal escape code. It should work beautifully on everything *but* Windows. Microsoft's cmd is a terminal wannabe.

I need it to clear the screen if
:
again == y

Then stick it in a while loop:
:
while (again == 'y')
{
    ...
}

That did not work

Did you set again first?
