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:
