Write a program to draw a chess board on an applet
Other chess applets exist and are also weak. The checkerboard contains 8 rows of squares and 8 columns. So, the understanding applet code not only involves color, graphics, and coordinates, but also controls flow structures and subroutines. By using JLayeredPane, I am able to use drag and drop for the piece.
As well as rendering a checkerboard and checkers, the GUI must allow a checker to be dragged from one square to another. I could have added longer look-aheads, but this would have caused delays and taken up too much memory.
So far i have created a plain chessboard using 8x8 GridLayout and 8x8 JP. Visualize that height is the vertical Y axis on a graph.
In that exercise, the code for drawing the board was in the paint method of a plain Applet. To write an applet that draws something, you need to know what subroutines are available for drawing.
Introduction An applet is a Java program that runs on a web page.

Consider this applet: The applet first fills its rectangle area with Cyan. Decrease the width and height. The parameter c is an object belonging to the Color class: "g. By using JLayeredPane, I am able to use drag and drop for the piece. Now, we have to determine whether the square in the row is Red. Fill in the entire applet using the g. I have sucessfully create a board and able to display chess pieces on the board. Set the rectangle width and height to be as big as the applet. If we had assumed that the rows are numbered 0, 1, 2, 3,.. To fill the rectangle with squares, a for loop iterates over 8 elements to form 8 rows, and 8 elements to form 8 columns. The if statement, as we know, executes a block of code if a condition has a boolean true. The squares are Red and Black.
Also, it enforces that white and black alternately make a move, white starting the game. Drawing an Image. I'm going to be, in the coming weeks, uploading tutorial after tutorial on Java!

The Point class is a new data type. This object is provided as a parameter to the paint routine when the system calls the paint method. So what I am asking for is as in Figure 7. An applet is not a stand-alone application, and it does not have a main routine. The complete code for this applet is in ImageDrawingApplet. As well as rendering a checkerboard and checkers, the GUI must allow a checker to be dragged from one square to another. Exercise 3. In Java, the built-in drawing subroutines are found in objects of the class Graphics, one of the classes of the java.
The parameters x, y, w, h must be integer-valued expressions.
