Help with deleting/printing linkedlist<object>

[delvinv]

Hey everyone,

I have a class called Student with attributes forename, surname [Strings] and StudentID[int].

Now, i have created a class called Registry (essentially a registry of Student(s)).
I have created a linkedlist called StudentList of type <Student>.

Using format, toString() methods i can successfully print them, but i need help with deleting a particular student using their studentId.
I wrote the following code

public void deleteStudent(int studentId) {
boolean found = false;
Student aStudent = studentList.getFirst();
it = studentList.listIterator();
while (found == false)
{
if (aStudent.getStudentId()==studentId)
{
it.remove();
System.out.println("Found and deleted!");
found = true;
}
else if (it.hasNext())
{
aStudent = (Student) it.next();
}
else
{
System.out.println("Error! Search query not found!");
found = true;
}
}

}
When i run it, it says successfully deleted, but when i run

System.out.println(student2.format()); //this is the student who i supposedly deleted.

I can still see the student in the linkedlist.

Please correct me where i am going wrong,

Please use [code] tags [/code] when posting code.
Assuming that you actually go through the block with the remove() call then it will have been removed from that list.
So, it'll be something in the code we cannot see that the problem lies.
For example, where is student2 declared and assigned?

I apologise for not putting it in code blocks. I have declared student2 in a seperate class called RegistryTester:

public class RegistryTester {

public static void main (String[] args){

Registry studentList = new Registry();    
System.out.println("Testing student register");
Student student1 = new Student("Ron", "Paul", 1001);
studentList.addStudent(student1);
Student student2 = new Student("Gary", "Shining", 1002);
studentList.addStudent(student2);

OK, and is that the 'student2' variable you call format() on?
Where do you call the method with the remove()?
You need to give us a bigger picture to work with.
For example:

Registry studentList = new Registry();
Student student2 = new Student("Gary", "Shining", 1002);
studentList.addStudent(student2); 
deleteStudent(1002);
System.out.println(student2.format());

That would at least show me the flow and the logic for the relevant variables.
