Condition

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 StudentStanding.java.

Code

import java.io.*;

public class StudentStanding {
    public static void main(String[] args) throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        Scanner scanner = new Scanner(System.in).useLocale(Locale.US);
        boolean isWorking = true;

            System.out.print("ID: ");
            int id = scanner.nextInt();
            System.out.print("First name: ");
            String firstName = bufferedReader.readLine();
            System.out.print("Last name: ");

            if (gradePointAverage >= 2.0) {
                BufferedWriter out = new BufferedWriter(new FileWriter("D:\\GoodStanding.txt", true));
                out.write("ID: " + Integer.toString(id));
                out.newLine();

                System.out.println(firstName + " " + lastName + " have grade point average > 2.0");
                System.out.println("This student was saved to GoodStanding.txt");
            } else {
                BufferedWriter out = new BufferedWriter(new FileWriter("D:\\AcademicProbation.txt", true));
                out.write("ID: " + Integer.toString(id));
                out.newLine();
                out.write("First name: " + firstName);
                out.newLine();
                out.write("Last name: " + lastName);
                out.newLine();
                out.write("Grade point average: " + Double.toString(gradePointAverage));
                out.newLine();
                out.newLine();
                out.close();
                System.out.println(firstName + " " + lastName + " have grade point average < 2.0");
                System.out.println("This student was saved to AcademicProbation.txt");
            }
            System.out.println("Continue? y - yes, n - no.");
            System.out.print("Answer: ");
            String answer = bufferedReader.readLine();
            if (answer.equals("y")) {
                System.out.println("");
            } else if (answer.equals("n")) {
                scanner.close();
                isWorking = false;
            }
        }
        System.out.println("Finished");
    }
}
