Java, Infinite Loop Issue

[Mikeyf619]

Hello Facepunch, I'm new to Java, and I'm trying to get this program to work, but it keeps crashing due to an infinite loop that I have no idea how to fix.

Here's the question...

[B]When The user enters the exponent at a promtp, the program displays 2 to that power. The program halts when the user enters -1[/B]

Here's what I have so far....

import java.util.Scanner;

public class Power{
	
	public static void main(String[] args){
		
		Scanner reader = new Scanner(System.in);
		
		System.out.print("Enter the exponent that will display 2 to that power: " );
		
		int x;
		x = reader.nextInt();
		
		int y = -1;
		
		while ( x > 0 ){
			
			System.out.println(Math.pow(2, x));
			
		
		}
		
		
		System.out.println( +x );
		
		
		
		
		
		
		
	}
	
	
	
	
}

The problem here is an infinite loop....

Please and Thank You

you need to update x in the loop

try this:

import java.util.Scanner;

public class Power
{	
	public static void main(String[] args)
	{
		Scanner reader = new Scanner(System.in);

		System.out.print("Enter the exponent that will display 2 to that power: ");

		int x = reader.nextInt();

		while(x != -1)
		{
			System.out.println(Math.pow(2, x));
			x = reader.nextInt();
		}
	}
}

Thank You very much, Now I Just have to figure out how to make the program halt when the user enters -1

EDIT:

Never mind, it seems you already did that for me, Thank you again.

Now, I'm going to try and make it so the user can enter any base they want

[NovembrDobby]

it does already ;p
