To create a window, where all the elements of the game are draw, we use the window class of JPlay package.

The class constructor is as follows:

						public Window(int width, int height); 
					

In the place of "width" we put the value of the window width in pixels.
In the place of "height" we put the value of the window height in pixels.

Note: Everytime we create a game using JPlay, we must first create a window and then, all the other components of the game. This procedure is obligatory, if not made several execution errors will occur.

Example: Create and display a borderless window with gray color

						package Window;

						import JPlay.Window;

						/**

						public class Window001
						{
							//Creates and shows a gray window without borders.
							//To quit press alt + F4
							public static void main(String[] args)
							{
								//It creates a window with 800 pixels of width and 600 pixels of height
								///This command always has to be the first to be executed.
								Window window = new Window(800,600);
							}
						}
