Question 1

Explain why an abstract method cannot be declared private.

Question 2

For the questions below, imagine that you want to implement a "Movie Cost" program that will use a GUI to obtain from the user the time of the movie and the number of people that need tickets, and will compute the cost. The GUI will use a JComboBox to obtain the time of movie (one of "Matinee", "Rush hour" or "Normal") and a JSlider to obtain the number of people (the JSlider goes from 1 to 10 and defaults to 1) and a JButton that says "Compute".

Write the code needed to set up the GUI as a JFrame that includes the JComboBox, the JSlider, the JButton and a JLabel used to output the total cost. The JLabel should initially display "Compute Movie Cost." Use the names jcb, js, jb and jl for the JComboBox, JSlider, JButton and JLabel respectively.
