In Java:

DrawPanel.java ( 30 points ) Override the method paintComponent to produce the following pattern:

Use a loop to draw 5 overlapping rectangles (see sample output below) ( 8 points ) All rectangles touch the top of the DrawPanel (the small space on the top is the empty border of the contentPane and it has nothing to do with the drawing)

Each rectangle has a random color that is white, yellow, orange, red, blue, or black ( 5 points ) (colors change when the window is resized see sample outputs below)

When the colors of adjacent rectangles are different (like in the sample output below) all the rectangles except for the top one in the center, appear as U-frames and the area shown has the same width ( 20 ) on all three sides: left, right, bottom. ( 5 points )

The smallest rectangle in the center has width 40 ( 3 points )

The distance between the left side of the DrawPanel and the largest rectangle is 100 ( 3 points )

The height of the largest rectangle is 200 ( 3 points )

Once you have a working program refactor your code. Watch out for meaningful names, simplify mathematical expression where appropriate to make the code clear and easy to read, avoid redundancy, and watch out for proper indentation. ( 3 points )

public class DrawPanel extends JPanel {

@Override

protected void paintComponent(Graphics g) {

super.paintComponent(g);

// g.setColor(Color.RED);

// g.fillRect(50, 50, 100, 100);

}

}

Output:

The main issue is how do I get them to overlap without covering up the rectangles behind them so that it will match the conditions up top.
