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.

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!

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.
