Question

6. Joe's Automotive

Joe's Automotive performs the following routine maintenance services:

• Oil change—$26.00

• Lube job—$18.00

• Radiator flush—$30.00

• Transmission flush—$80.00

• Inspection—$15.00

• Muffler replacement—$100.00

• Tire rotation—$20.00

Joe also performs other nonroutine services and charges for parts and for labor ($20 per hour). For that allow Joe to enter the number of hours. Also, the cost of parts if applicable. The customer may ask for more than one service.

Create a GUI application that displays the total for a customer's visit to Joe's.

Answer 1

Answer:-

The below is the required source code for the given problem

Code:-

public class Service extends JPanel

{

public final double OIL_CHANGE = 26.00;

public final double LUBE_JOB = 18.00;

public final double RADIATOR_FLUSH = 30.00;

public final double TRANSMISSION_FLUSH = 80.00;

public final double INSPECTION = 15.00;

public final double MUFFLER_REPLACEMENT = 100.00;

public final double TIRE_ROTATION = 20.00;

private JTextField calcTextField;

private JCheckBox Oil_change;

private JCheckBox Lube_job;

private JCheckBox Radiator_flush;

private JCheckBox Transmission_flush;

private JCheckBox Inspection;

private JCheckBox Muffler_replacement;

private JCheckBox Tire_rotation;

public Service()

{

setLayout(new GridLayout(7,1 ));

Oil_change = new JCheckBox("Oil Change ($26.00)");

Lube_job = new JCheckBox("Lube Job ($18.00)");

Radiator_flush = new JCheckBox("Radiator Flush ($30.00)");

Transmission_flush = new JCheckBox("Transmission Flush ($80.00)");

Inspection = new JCheckBox("Inspection ($50.00)");

Muffler_replacement = new JCheckBox("Muffler Replacement ($100.00)");

Tire_rotation = new JCheckBox("Tire Rotation ($20.00)");

setBorder(BorderFactory.createTitledBo… Services"));

add(Oil_change);

add(Lube_job);

add(Radiator_flush);

add(Transmission_flush);

add(Inspection);

add(Muffler_replacement);

add(Tire_rotation);

public double actionCalculate()

{

double total = 0;

if(Oil_change.isSelected())

total = total + OIL_CHANGE;

if(Lube_job.isSelected())

total = total + LUBE_JOB;

if(Radiator_flush.isSelected())

total = total + RADIATOR_FLUSH ;

if(Transmission_flush.isSelected())

total = total + TRANSMISSION_FLUSH;

if(Inspection.isSelected())

total = total + INSPECTION;

if(Muffler_replacement.isSelected())

total = total + MUFFLER_REPLACEMENT;

if(Tire_rotation.isSelected())

total = total + TIRE_ROTATION;

return total;

}

}

//This for NonRoutine Services

public class NonService extends JPanel

{

public final double perHourCharge = 20.00;

private JLabel partsLabel;

private JLabel laborLabel;

private JTextField partsTextField;

private JTextField laborTextField;

private JPanel panel;

public NonService()

{

partsLabel = new JLabel("Parts Charges:");

laborLabel = new JLabel("Hours of Labor:");

partsTextField = new JTextField(10);

laborTextField = new JTextField(10);

setBorder(BorderFactory.createTitledBo… services"));

add(partsLabel);

add(partsTextField);

add(laborLabel);

add(laborTextField);

panel = new JPanel();

panel.setLayout(new GridLayout(3,2));

setLayout(new GridLayout(2, 2));

}

}

public class CalculatorGUI extends JFrame

{

private Service sc;

private NonService ns;

private JPanel buttonPanel;

private JButton calcButton;

private JButton exitButton;

public CalculatorGUI()

{

super("Joe's Automotive");

setLocationRelativeTo(null);

setDefaultCloseOperation(JFrame.EXIT_O…

setLayout(new BorderLayout());

sc = new Service();

ns = new NonService();

buildButtonPanel();

add(sc, BorderLayout.NORTH);

add(ns, BorderLayout.SOUTH);

pack();

setVisible(true);

}

private void buildButtonPanel()

{

buttonPanel.add(calcButton);

buttonPanel.add(exitButton);

}

private class CalcButtonListener implements ActionListener

{

public void actionPerformed(ActionEvent e)

{

double total;

total = sc.actionCalculate() +ns.getNonroutineServicesCost();

DecimalFormat dollar = new DecimalFormat("0.00");

JOptionPane.showMessageDialog(null, "Total: $" +dollar.format(total) );

}

}

private class ExitButtonListener implements ActionListener

{

public void actionPerformed(ActionEvent e)

{

System.exit(0);

}

}

public static void main(String args[])

{

new CalculatorG
