Programming

1.      Plan your logic before working on the project and review the syntax you will use in the project. Think about how you want the output to be displayed to the user. You might want to tell the user what the program does and what type of input you expect from the user. You interface structure could do this. Select names of the variables you will use in the program.

2.      Create a JAVA project Using NetBeans IDE. And have the code window open to write the project code. Here are some instructions on creating the project.

·         Declare variables to hold input information.

·         Using the JOptionPane Concept. (Some programs might need just the Scanner.

·         Ask the user to enter some information requested and save the response to a variable. This could look like: name = JOptionPane.showInputDialog (“Enter your name”).

·         Use line spacing (i.e. \n) to separate lines of output to make it easy for the user to read the information and have proper line length.

3.   Documentation: All lines of code must be documented.

·         Use the syntax to designate lines in code as comments (//)

·         These comments can be at the end of a line of code or in a group definition at the beginning of a section of code. All methods and function need a group heading document.

4.   Run the program using Run Project menu item.Debug the code, making sure all calculations are correct and the line spacing is suitable for readability.

Assignment

A movie theater only keeps a percentage of the revenue earned from ticket sales. The remainder goes to the movie company. Create an application that calculates and displays the following figures for one night’s box office business at a theater:

Create a GUI application that allows the user to enter the following data into text fields:

·         Price per adult ticket

·         Number of adult tickets sold

·         Price per child ticket

·         Number of child tickets sold

The application should calculate and display the following data for one night’s box office business at the theater:

• Gross revenue for adult tickets sold. This is the amount of money taken in for all adult tickets sold
• Net revenue for adult tickets sold. This is the amount of money from adult ticket sales left over after the payment to the movie company has been deducted.
• Gross revenue for child tickets sold. This is the amount of money taken in for all child tickets sold.
• Net revenue for child tickets sold. This is the amount of money from child tickets sales left over after the payment to the movie company has been deducted.
• Total gross revenue. This is the sum of gross revenue for all adult and child tickets sold.
• Total net revenue. This is the sum of net revenue for adult and child tickets sold.

Assume the theater keeps 20% of the box office receipts. Use a named constant in your code to represent this percentage.

Use the following set of test data to determine whether the application is calculating properly.
