Question

The following code creates a calculator but it is not the correct color. What do I change to make it a checkerboard pattern?

import javax.swing.*;

import java.awt.*;

public class myCalculator extends JFrame{

private static final long serialVersionUID = 1L;

private Color lightCyan;

private Font font1;

public myCalculator()

{

// Call the super class JFrame and set the title of the window to My Calculator Class

super.setTitle(" My Calculator Class");

Color paleCyan = new Color(109, 207, 246);

setLightCyan(new Color(68, 140, 203));

//Set the font type and style

setFont1(new Font("SansSerif", Font.BOLD, 16));

// In a real calculator these is where your calculations appear!

JTextField jtext = new JTextField(" 0 ");

jtext.setSize(250,25);

jtext.setHorizontalAlignment(JTextField.RIGHT);

JPanel textPanel = new JPanel(new BorderLayout());

/* Main Panel holding the JText field for the calculations area is used with the BorderLayout because the NORTH portion stretches

the JTextfield Horizontal (side-to-side) */

textPanel.add(jtext, BorderLayout.NORTH);

JPanel buttonsPanel = new JPanel(new GridLayout(4,4,5,5));

buttonsPanel.setBackground(paleCyan);

JButton jTwo = new JButton("2");

JButton jOne = new JButton("1");

JButton jThree = new JButton("3");

JButton jFour = new JButton("4");

JButton jFive = new JButton("5");

JButton jSix = new JButton("6");

JButton jSeven = new JButton("7");

JButton jEight = new JButton("8");

JButton jNine = new JButton("9");

JButton jZero = new JButton("0");

JButton jDot = new JButton(".");

JButton jEqual = new JButton("=");

JButton jMultiply = new JButton("*");

JButton jDivide = new JButton("/");

JButton jMinus = new JButton("-");

JButton jAdd = new JButton("+");

buttonsPanel.add(jSeven);

buttonsPanel.add(jEight);

buttonsPanel.add(jNine);

buttonsPanel.add(jMultiply);

buttonsPanel.add(jFour);

buttonsPanel.add(jFive);

buttonsPanel.add(jSix);

buttonsPanel.add(jOne);

buttonsPanel.add(jTwo);

buttonsPanel.add(jThree);

buttonsPanel.add(jMinus);

buttonsPanel.add(jDot);

buttonsPanel.add(jZero);

buttonsPanel.add(jEqual);

buttonsPanel.add(jAdd);

JPanel mainPanel = new JPanel(new BorderLayout());

//Final step add the panels to the Frame (Container)

mainPanel.add(textPanel, BorderLayout.NORTH);

mainPanel.add(buttonsPanel, BorderLayout.CENTER);

add(mainPanel, BorderLayout.CENTER);

}

public static void main(String[] args) {

myCalculator frame = new myCalculator();

frame.setSize(250, 250);

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setResizable( false );

frame.setVisible(true);

}

public Font getFont1() {

return font1;

}

public void setFont1(Font font1) {

this.font1 = font1;

}

public Color getLightCyan() {

return lightCyan;

}

public void setLightCyan(Color lightCyan) {

this.lightCyan = lightCyan;

}

}

Need to change color from of first picture to the second.
