    Default Guessing game

    Is there actually a specific thread to post your games? This is my first guess, and I'm not here to show off or I'll be fooling myself here as it's not the best game. I'm actually just asking for any general advice on my code such as better structuring, etc (I do know about classes but the code is short so it's pointless).

    import javax.swing.JOptionPane;
    import java.util.Random;
     
    public class Window {
    	public static void main(String[] args)
    	{
    		//hold data
    		Random rnd = new Random();
    		int RandomNumber = rnd.nextInt(1001);
    		int low = 0, high = 1000;
    		int Number = 0;
     
    		String GetText;
     
    		// main loop
    		do
    		{
    			GetText = JOptionPane.showInputDialog("Guess the number(" + low + "-" + high + "):");
     
    			Number = Integer.parseInt(GetText);
     
    			if (Number > RandomNumber)
    			{
    				JOptionPane.showMessageDialog(null, "Lower!", "Guess The Number!", JOptionPane.PLAIN_MESSAGE);
    				high = Number;
    			}
    			else if (Number < RandomNumber)
    			{
    				JOptionPane.showMessageDialog(null, "Higher!", "Guess The Number!", JOptionPane.PLAIN_MESSAGE);
    				low = Number;
    			}
    		} while (Number > RandomNumber || Number < RandomNumber);
     
    		JOptionPane.showMessageDialog(null, "You are a winner", "Congratulations!!!", JOptionPane.PLAIN_MESSAGE);
    	}
    }

    Comments:
    Window and Number are the names of a Java SE classes. It'd be better to use other names
    Java naming conventions are that variable names start with lowercase letters.
    There isn't a test for when the numbers are equal. That could be handled by a comment saying the loop exits when they are equal
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks for the suggestions, I will keep them in mind.

    while (Number > RandomNumber || Number < RandomNumber)

    If the number isn't higher or lower then it must be equals that's when it finishes and shows the congratulations message.

    A comment makes the programmer's intentions clearer.
