Week03_Chapter03_Lab Chapter 3 Lab Introduction to Software Lab Description: You will be creating a program that will calculate the GPA of a single semester based on the overall scores of one course. Naming Requirements: These are the names you are required to use for your lab project. Make sure the letter casing is also the same (for example, Example.java is not the same as example.java). Java file name: GpaCalculator.java Main class name: GpaCalculator Core Requirements: PART 1: Prompt the user to enter the overall percentage for a single class. For now, we will assume that the percentage will range from 0.0 through 100.0. This percentage should be stored in a variable. You do not need to perform validation to make sure that the scores are correct. You will learn how to do this in a later week. PART 2: Determine the letter grade based on the percentage provided. Use the following scale: For scores greater than or equal to 97.0 "A+" For scores greater than or equal to 93.0 For scores greater than or equal to 90.0 "A." For scores greater than or equal to 87.0 " B " For scores greater than or equal to 83.0 "B" For scores greater than or equal to 80.0 "B." For scare creater than or equal to 77.0 Week03_Chapter03_Lab For scores greater than or equal to 93.0 "A" For scores greater than or equal to 90.0 For scores greater than or equal to 87.0 "B " For scores greater than or equal to 83.0 "B" For scores greater than or equal to 80.0 "B." For scores greater than or equal to 77.0 *C+" For scores greater than or equal to 70.0 "C" For scores greater than or equal to 67.0 "D " For scores greater than or equal to 60.0 "D" For all other scores "F" And based on the letter grade, determine the GPA based on the following scale: . "A+"- 4.0 "A" - 4.0 . "A" 3.7 "B+" - 3.3 "B" - 3.0 "B" 2.7 "C+"-2.3 "C" - 2.0 "D+" - 1.7 . "D" 1.0 "F" 0.1 PART 3: Display the results. Display all of the results to the user. Make sure the information is properly labeled so that the user understands what they are reading. This means you should display: The percentage given by the user. The letter grade. The GPA
