Results are not the same at the end and I do not get the right result after choosing number 3. The images below is how it should look like going from entering first student to printing information of a faculty. Here's part of my code :
class UniversityPersonnelManagement {
public static void main(String[] args) {
//create list to store Student objects
ArrayList<Student> studentList = new ArrayList<Student>();
//create list to store Faculty objects
ArrayList<Faculty> facultyList = new ArrayList<Faculty>();
System.out.println("Welcome to my Personal Management Program");
for (;;) {
int input = 0;
System.out.println(" Choose one of the options:");
System.out.println("1- Add a new Faculty member");
System.out.println("2- Add a new Student");
System.out.println("3- Print tuition invoice for a student");
System.out.println("4- Print information of a faculty");
System.out.println("5- Exit Program");
System.out.print("\n Enter your selection: ");
Scanner s = new Scanner(System.in);
try {
input = s.nextInt();
s.nextLine();
} catch (Exception e) {
System.out.println("Invalid entry- please try again");
}
if (input == 1) {
Faculty f = new Faculty();
System.out.println("\tEnter the faculty’s info:");
System.out.print("\tName of the faculty:");
f.fullName = s.next();
System.out.print("\tID:");
f.ID = s.nextLine();
// s.nextLine();
for (;;) {
String rank;
System.out.print("\tRank:");
rank = s.next();
if (rank.equalsIgnoreCase("professor") || rank.equalsIgnoreCase("adjunct")) {
f.Rank = rank;
break;
} else {

//flag to keep track of if student found
boolean studentFound = false;
while (si.hasNext()) {
stnt = si.next();
//if id already there
//for comparing string if both are equal or not
//use equals method
if (stnt.ID .equals(id)) {

stnt.generateTuituonInvoice(stnt);
//student exist set flag to true

break;

}
//if student with given id not found
