a. Create an application that allows you to enter student data that consists of an ID number, first name, last name, and grade point average. Depending on whether the student’s grade point average is at least 2.0, output each record either to a file of students in good standing or those on academic probation. 

Save the program as StudentsStanding.java.

b. Create an application that displays each record in the two files created in the StudentsStanding application in Exercise 8a. Display a heading to introduce the list produced from each file. For each record, display the ID number, first name, last name, grade point average, and the amount by which the grade point average exceeds or falls short of the 2.0 cutoff. Save the program as StudentsStanding2.java.
