(TCOs 1–6) TicketsRUs needs an application to calculate ticket prices. There are three ticket

prices:

·           Orchestra    $85 each

·           Mezzanine   $70 each

·           Balcony      $45 each

There is also a 15% discount on matinee performances.

Your application has the GUI shown below.

With the following named components:

Component

Type

Purpose

txtNum

JTextField

Input for number of tickets

chkMatinee

JCheckBox

Check if matinee performance

radOrchestra

JRadioButton

Check for orchestra tickets

radMezzanine

JRadioButton

Check for mezzanine tickets

radBalcony

btnCalc

JButton

Click to calculate price

txtEach

JTextField

Displays price of each ticket

txtTotal

JTextField

Displays total price

Clicking the CalcPrice button should determine the price per ticket and the total price based on the user’s input and display in txtEach and txtTotal. You should make sure the number of tickets is entered and a ticket type is selected, otherwise give an error message.

The action listener for btnCalc is set up as follows.

btnCalc.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

                 calcPrice(); //write the code for this method

}

});

Write the calcPrice method that is called by the action listener. This class method has access to all of the GUI components. You DO NOT HAVE TO CODE THE GUI. ONLY write the code for this method which does all the work. The header for the method is:

private void calcPrice
