Module Six Assignment Guidelines and Rubric - D 5x Overview Many Java programs that you create will receive and process user input. In order to ensure that user input is accurate, you will need to use input validation and exception handling. For example, if you ask for a zip code, you want to ensure the user inputs a five-digit number. In this activity, you are given "buggy" code for a paint program. This program calculates the number of cans of paint required to paint a wall, given the wall's height and width. You will first need to debug the existing code. Then you will improve it by adding code to validate user input and handle exceptions. Prompt For this assignment, you will complete the paint program by debugging the original code and adding code that validates user input and handles exceptions. 1. Before you begin, 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. Use the Uploading Files to Eclipse Tutorial PDF to help you with this step. 2. First, you will debug the Paint1 class so that no errors remain and all calculations work correctly by completing the following: - Find and fix the three errors in the given code. - Use the following sample input values to test your program. If you have found and fixed all the errors, your output should exactly match the sample. learn.snhu.edu/d2l/le/content/1230291/viewContent/22517487/View 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. 3. Next, you will add loops to validate all user input and handle exceptions so that code passes all test cases by completing the following: - 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. - Use the two following sample sets of input to test your program. Since these inputs are invalid, your program should respond to each by prompting the user to enter valid input. This should continue to loop until valid input is received. Think: Why is 0 invalid input for this problem? What is the user being asked to input? Guidelines for Submission Submit your completed Paint1.java file.
