I need help creating a square that is empty. The square would have the same number of asterisks on each side. The size is decided on user input. I just have an issue on understanding nested loops please help.

public class square
{
	public static void main(String[] args)
	{
		//declare keyboard as scanner type
		Scanner keyboard = new Scanner(System.in);
		//get input from the user
		System.out.print("Please enter a value of height (1-20): ");
		//declare height as int
		int height = keyboard.nextInt();
		//Run a group of nested for loops to make a square
			for(int i = 0; i < height; i++)
			{
				for(int j = 0; j <= height; j++);
					{
						System.out.print('*');
					}
				System.out.println();

This look like java... this is the javascript section, you should try posting it in the right section you will have more chance of getting help
Plus it seem that you miss the end of your code

This really look like a school homework, so we can't give you the answer, but look at the line System.out.print('*'); if you want en empty square, you should think of putting a condition near it
if it is not the first or last row and if it is not the first or last columns
