1 CIS 265 Data Structures and Algorithms Assignment 5, 100 points Due: 12:25pm, Mar. 10, 2021 I. General Description In this assignment, you will create a Java program to read undergraduate and graduate students from an input file, and write them in reverse order to an output file. 1. The input file name and the output file name are passed in as the first and second arguments at command line, respectively. For example, assume your package name is FuAssign5 and your main class name is FuAssignment5, and your executable files are in “C:\Users\2734848\eclipse-workspace\CIS 265 Assignments\bin”. The following command line will read from a local file “students.txt” and write to a local file “students_reversed.txt”: C:\Users\2734848\eclipse-workspace\CIS 265 Assignments\bin > java FuAssign5.FuAssignment5 students.txt students_reversed.txt 2. You need to specify the command line arguments if you use jGrasp or Eclipes. I will show you on jGrasp on Wed. 3. The parameter String[] args in the main method contains the command line arguments, where args[0] contains the first argument. For example, in the previous command, args[0] contains students.txt, and args[1] contains students_reversed.txt. 4. If the program is run with incorrect number of arguments, your program must print an error message and exit. The error message must show correct format to run your program, e.g., “Usage: FuAssign5.FuAssignment5 input_file output_file” where FuAssign5 is the package and FuAssignment5 is the main class. 5. Each line in the input file represents a student. There are 5 fields in each line: name, id, gpa, “graduate” or “undergraduate”, isTransfer (for undergraduate) or college (for graduate). The fields are separated by comma, “,”. For example, the input file students.txt file may contain: Michelle Chang,200224,3.3,graduate,Cleveland State University Tayer Smoke,249843,2.4,undergraduate,false David Jones,265334,2.7,undergraduate,true Abby Wasch,294830,3.6,graduate,West Virginia 6. The program will read the lines and create undergraduate students or graduate students accordingly. The students are added to an ArrayList. 7. The program then writes the list of students in reserve order to the output file. 8. Given the previous input file students.txt, the output file, students_reserved.txt, will be: Abby Wasch,294830,3.6,graduate,West Virginia David Jones,265334,2.7,undergraduate,true Tayer Smoke,249843,2.4,undergraduate,false Michelle Chang,200224,3.3,graduate,Cleveland State University II. Implementation Requirements The program must implement a main class and three student classes (Student, UndergradStudent, GradStudent). • You may reuse the code from previous assignments. 2 • However, the Student class must be declared as an abstract class now. It must also have an overloaded printStudent(PrintWriter output) method. The method will write student’s information to the output file
