Part II: Reading a Data File Review the program Warning java that reads in a file of student academic credit data. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). Here is the students.dat data file: students.dat Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 Wood 100 400 Street 33 57.4 Taylor 83 190 Davia 110 198 Smart 75 292.5 Bird 84 168 Summers 52 83.2 The program should compute the GPA (grade point or quality point average) for cach 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: • AFileNotFoundException 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.
