Requirements:

Student information is stored in a text file named p02-students.txt. There is one student record per line, where the format of a student record for an on-campus student is:

C id last-name first-name residency program-fee credits where:

'C'
id last-name first-name residency program-fee credits

Identifies the student as an on-campus student.
The student identifier number. A string of 13 digits.
The student's last name. A contiguous string of characters.
The student's first name. A contiguous string of characters.
'R' if the student is a resident, 'N' if the student is a non-resident. A program fee, which may be zero.
The number of credit hours for which the student is enrolled.

The format of a student record for an online student is:

O id last-name first-name tech-fee credits

where 'O' identifies the student as an online student, and id, last-name, first-name, and credits are the same as for an on-campus student. The tech-fee field is 'T' if the student is to be assessed the technology fee or '-' if the student is not assessed the technology fee.

Explanation / Answer

This program will calculate the total tuition and fees for students import javax.swing.*; import java.text.*; public class Tuition { public static String dialogTitle = "Tuition and Fees Calculator"; //want dialogTitle to be the same for most dialogs //ensure newline is cross-platform. Taken from http://leepoint.net/notes-java/io/10file/sys-indep-newline.html public static String newline = System.getProperty("line.separator"); //main method overloading; for restarting app public static void main(String[] args) { main(""); } //overloaded main method. was easier for me to check for a null string than it was to check for a null string array. public static void main(String args) { int hours; double fees, rate, tuition; if (args == "") displayWelcome(); //display welcome message unless arguments are passed in hours = getHours(); //ask user for number of hours rate = getRate(hours); //get the cost per credit hour rate tuition = calcTuition(hours, rate); //calculate the tuition fees = calcFees(tuition); //calculate the fees displayTotal(tuition + fees); //display the result to the user finish(""); //user is finished, end the program (without asking) } //display the welcome message to the user public static void displayWelcome() { String welcomeMsg = "Welcome to the Tuition and Fees calculator!"; JOptionPane.showMessageDialog(null, welcomeMsg, dialogTitle, JOptionPane.PLAIN_MESSAGE); } //ask the user for number of hours public static int getHours() { String strHours, askHours; int hours = 0; boolean done = false; askHours = "Please enter the total number of course hours the student will be attending:"; //continue asking user until user provides valid input while (!done) { strHours = JOptionPane.showInputDialog(null, askHours, dialogTitle, JOptionPane.QUESTION_MESSAGE); if (strHours == null) {finish("ask");} //user cancelled the dialog. ask if user is sure before quitting. else { try { hours = Integer.parseInt(strHours); if (hours
