Java Question 36

TicketsRUs needs an application to calculate ticket prices. There are three ticket prices: Orchestra $90 each Mezzanine $75 each Balcony $50 each There is also a 20% 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	JRadioButton	Check for balcony tickets
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 users 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()
