My problem is in Eclipse and using Tests to run the code. The original test is also broken.

The code provided below displays nine panels of different colors in a 3 X 3 grid. Whenever the mouse enters a panel, it turns magenta; when the mouse leaves, the color reverts back to its original color. Add the following user story: "When the user clicks on the center panel, the colors of the eight surrounding panels rotate to the next panel in a clockwise direction." Remember to TDD.

When complete, add this user story: "When the user consecutively clicks on two of the outer panels, the colors of these panels are swapped."

import java.awt.Color;

import java.awt.GridLayout;

import javax.swing.JFrame;

public class Init {

public JFrame jFrame;

MyJPanel panels[];

Color colors[] = { Color.blue, Color.green, Color.red, Color.white, Color.yellow, Color.black, Color.orange,

Color.cyan, Color.gray };

public Init() {

panels = new MyJPanel[9];

jFrame = new JFrame("NINE SQUARES PROGRAM");

jFrame.setSize(500, 500);

jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

jFrame.getContentPane().setLayout(new GridLayout(3, 3));

for (int i = 0; i < panels.length; i++) {

panels[i] = new MyJPanel(colors[i]);

jFrame.getContentPane().add(panels[i]);

}

jFrame.setVisible(true);

}

public static void main(String[] args) {

new Init();

}

}
