The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours), and display the student name if the gpa is less than 2.0. The file Warning.java contains a skeleton of the program. Do the following: 1. Add the code to calculate the gpa. 2. Display the name if the gpa is less than 2.0. 3. Test to ensure the output is accurate. 4. Add code to catch the following exceptions: • A FileNotFoundException if the input file does not exist. How will you test for this exception? • A NumberFormatException if it can’t parse an int or double when it tries to – this indicates an error in the input file format. How will you test for this error? Display the record number in error.
