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
