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
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 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()
