Part 1: Create a program in Eclipse to: -Calculate the overall GPA for a student (rounding two decimal places) -Assume the user took four classes in the semester -For each of the four classes (just copy the steps below 4 times) -Ask user for the credit hours of the course -Ask user for the letter grade received in the course *Make sure code works for upper and lower case grades* Part 2: -Add a simple error check so only the grades A,B,C,D, or F will be accepted. Otherwise, an error message is produced ("Invalid Grade") and the program will exit. Please make sure the program is compatible with Eclipse software
