Storing in an array from my own created class

Question

Hi,
Here I am again with more questions. I am grovelling for help.
I am working on a program in Netbeans 5.5.1 where I created a class called Student that gets and sets Last Name, First Name and Student ID. Now the program to run as a samle of this class will store the first Student I get and put it into slot [0] of my array and then I increment my NumStudents, as a count to moveon to the next array slot. The problem is that it only puts the Student info into slot[0], even on the 2nd or 3rd entry to store information. I'm not sure if the problem is in the gets and sets in my class or in my Store Info button listener.
Here is a bit of the code. I have comments to help explain my problem.
Thank you oh virtuosos of Java! This stuff brings me to tears!
private void mouseclickedbtnStoreInfo(java.awt.event.MouseEvent evt)
// Code to store info from the textbox entered by user:
s.setFirstName(txtFirstName.getText());
s.setLastName(txtLastName.getText());
s.setStudentID(txtStudentID.getText());
arrayAllStudents[NumStu] = s;
NumStu++;
txtFirstName.setText("");
txtLastName.setText("");
txtStudentID.setText("");
//Testing array storage here also
/*This only prints out only for the second student entered, loses the first, NumStu times, apparently only storing in slot 0. array is of Student class as is the variable s.*/
for(int i=0;i<NumStu;i++){
System.out.println(arrayAllStudents.getStudentID());
System.out.println(arrayAllStudents[i].getFirstName());
System.out.println(arrayAllStudents[i].getLastName());
Hopefully this is not a challenging puzzle for all you experts out there. Pop me a line soon. I'll take my turn helping when I get this #*@& figured out.

O.k. I'll try this again. We'll see if anything is clearer with this code. Before this I also have automatically generated code from Netbeans coding my gui. I also have another page of code generating my Student.class. The only methods I have in that are the sets and gets of StudentID, LastName, and FirstName.
    private void mouseclickedbtnStoreInfo(java.awt.event.MouseEvent evt) {                                         
// Code to store info from the textbox entered by user:
        s.setFirstName(txtFirstName.getText());
        s.setLastName(txtLastName.getText());
        s.setStudentID(txtStudentID.getText());
        arrayAllStudents[NumStu] = s;
        NumStu++;
        txtFirstName.setText("");
        txtLastName.setText("");
        txtStudentID.setText("");
        //Testing array storage here also
        //This only prints out only for the second student entered and loses the first NumStu times
        for(int i=0;i<NumStu;i++){
            System.out.println(arrayAllStudents.getStudentID());
System.out.println(arrayAllStudents[i].getFirstName());
System.out.println(arrayAllStudents[i].getLastName());
private void mouseClickedRetrieveInfo(java.awt.event.MouseEvent evt) {                                         
// Code for user to retrieve the info from textboxes:
//This is all printing out as only the last student entered but as many times as Num##.
for(int i=0;i<NumStu;i++){
System.out.println(arrayAllStudents[i].getStudentID());
System.out.println(arrayAllStudents[i].getFirstName());
System.out.println(arrayAllStudents[i].getLastName());
* @param args the command line arguments
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new frmTestStudentClass().setVisible(true);
// Variables declaration - do not modify
private javax.swing.JButton btnRetrieveInfo;
private javax.swing.JButton btnStoreInfo;
private javax.swing.JLabel lblFirstName;
private javax.swing.JLabel lblLastName;
private javax.swing.JLabel lblStudentID;
private javax.swing.JTextField txtFirstName;
private javax.swing.JTextField txtLastName;
private javax.swing.JTextField txtStudentID;
// End of variables declaration
Student s;
Student arrayAllStudents[] = new Student[MaxStu];
}This does compile and run the gui. User can enter text into the textboxes and when I hit my StoreInfo button the textboxes clear and NumStu is incremented and first entrance is stored in arrayAllStudents[0].  This seemed to paste just as it is in Netbeans.
