paint program

For complete instruction follow the attached pdf file.

For this assignment, you will complete the paint program by debugging the original code and adding code that validates user input and handles exceptions. Use the Uploading Files to Eclipse and the Downloading Files from Eclipse Tutorial tutorials to help you with this project.

  • Debugging
    • Open the Virtual Lab by clicking on the link in the Virtual Lab Access module. Then open your IDE. Upload the Paint1.zip folder and review the code for the Paint1.java file.
    • Find and fix the three errors in the given code.
    • Use the input values below to test your program. If you found and fixed all errors, your output should exactly match what is below.
      TIP: When you run your program in Eclipse, it will prompt you to enter input in the Console window. If you cannot find this window, go to Window, then Show View, then Console.

Input value table with the numerals 30 and 25

Output value table with the wall area as 750.0 square feet and the paint needed as 2.142857142857143 gallons

  • Input Validation and Exception Handling
    • Review the code, looking for the two code blocks where user input is required.
    • Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled.
      TIP: Consider using a try-catch block for exception handling, but it is not required.
    • Use the two sample invalid inputs below to test your program. Your program should respond to each by prompting the user to enter valid input. This should continue to loop until valid input is received.

A table with two columns titled Input 1 and Input 2. The items under Input 1 are the spelled-out number thirty and the numeral 25. The items under Input 2 are the numerals 30 and 0.

THINK: Why is 0 invalid input for this problem? What is the user being asked to input?
