INTRO TO JAVA PROGRAMMING
The cost to become a member of a fitness center is as follows: (a) the Senior citizens discount is 30%; (b) if the membership is bought and paid for 12 or more months in advance, the discount is 15%; or (c) if more than 5 personal training sessions are purchased, the discount on each session is 20%. Write a menu driven program that determines the cost of a new membership.
Your program must contain a method that displays the general information about the fitness center and its charges, a method to get all the necessary information to determine the membership cost and a method to determine the membership cost.
Use appropriate parameters to pass information in and out of a method.
The first screen of your GUI will show the cost of membership and all of the discount options. Use JTextArea on page 811 for this part.
Membership Cost: $500
Training Sessions Cost: $100 per session
List the discounts here: A: Senior citizens discount is 30%, B) 15% discount if the membership is bought and paid for 12 or more months in advance, C) if more than 5 personal training sessions are purchased, the discount on each session is 20%.
Then you need to get the input from the user like on page 354, using JTextField for the input, Jlabel to describe what you want them to input and some buttons. (Calculate, Exit)
1. The user can choose 1 or 2 (Yes, No) for Senior or it can be a yes or no input.
2. Have the user enter number of months, or you can give them choices. 6, 12, 18 month options.
3. Have the user enter number of training sessions they wish to purchase.
4. Finally, when the user clicks on the Calculate button. You will show their membership cost.
PLEASE MAKE JAVA CODE SHORT AND EASY AND PLEASE ADD COMMENTS SO I CAN UNDERSTAND THE PROCESS
811 HTML file for this program contains the following c Additional GUI Components height "50"> Additional GUI Components The remainder of this chapter introduces GUI components in addi duced in Chapter 6. For the most part, these additional GUI compon same way as the ones introduced earlier. For example, you create using the operator new. If the program olcomponents are used in the Xample, you create an instance (or object) GUI onent, such as JTextField vide the associated method th omp needs to respond to an event occurring in a or JButton, you must add an event listener and at needs to be invoked, commonly called the event We will also illustrate the use of various method s of the class Graphics JTextArea The GUI programs in display a line of text. However, there are situations when the program must multiple lines of text. For example, an employee's address is shown in three or more lines. Because an object of the class JText cannot use an object of this class to display multiple lines of text. Java provides the class JTextArea to either collect multiple lines of input from the user or to display multiple lines of output. Using an object of this class, the user can type multiple lines of text, which are separated by pressing the Enter key. In Java, each line ends with the newline character 'n' previous chapters extensively used the class JTextField to display Field can display only one line of text, you The GUI part of the Student Grade Report programming example in Chapter 10, (available with the Additional Student Files at www.cengagebrain.com) uses a JTextArea to display multiple lines of text to show the various courses taken by a student and the student's grade for each course. This section discusses the capabilities of the class JTextArea in some detail. Both JTextField and JTextArea are derived from the class JTextComponent and as such, share many common methods. However, you cannot create an instance of the class JTextComponent because it is an abstract class. Table 12-8 1 constructors and methods of the class JTextArea of theExplanation / Answer
