Problem description Write a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. 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). 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) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students. Do the following: 1. Create a text data file "students.dat". The following shows part of a typical data file: Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 2. Set up a Scanner object scan from the input file and a Print Writer outFile to the out- put file inside the try clause. Note that you'll have to create the Print Writer from a FileWriter, but you can still do it in a single statement. 3. Prompt the user for a filename. If the user enters the name of a file that does not exist, ask for another name until you get one that refers to a valid file. 4. Inside the while loop add code to read and parse the input get the name, the number of credit hours, and the number of quality points. Compute the GPA, determine if the student is on academic warning, and if so write the name, credit hours, and GPA (separated by spaces) to the output file.
