Question

java programing
Class SquaresPanel is a JComponent that maintains a list ofsquares, can display them, and is able to generate a new square andadd it its list of squares. Here is the plan: in fields wehave SIDE (the length of the sides of each square), n (the numberof squares we have), and x and y (arrays that store the pixelcoordinates of their corners in indexes 0..n-1). Write a method ofSquaresPanel called addSquare that generates a random square andadds it to its list of squares. The generated square should beentirely contained within our area and equally likely to beanywhere. (Use getWidth() and getHeight() to determine theareas of this SquaresPanel.) java programing
