Exclamation Java Project Problem

I currently have one GUI window called 'Ossian'
and
one Class called 'Holiday'

this is a travel holiday package, which allows the user to input holidays, which are stored in an array then later saved to file. (the saved to file will be worryed about later) just now all im after is allowing the holidays to be stored in the array.
basically i've got 7 blank textboxes, where you insert holiday details into, then click the add button. It then adds that holiday to an array which can hold up to 50. the class holds all the varible's from the textboxes it has recived so they can be used around my program.

here is my code i attempted to do. it runs but i dont think its storing the values in the class at all. or im displaying it incorrectly.

all im trying to achive here is to add holidays to an array at this stage, the display was put in simply to see if it added at all.

am i coding this correctly to add a holiday to an array?

Main GUI

Code:
public class Ossian extends javax.swing.JFrame
{
static Holiday h[] = new Holiday[50];
static int count;

public Ossian()
{
initComponents();
}

public static void EnterHoliday()
{
jTextField1.setText("");
jTextField2.setText("");
jTextField3.setText("");
jTextField4.setText("");
jTextField5.setText("");
jTextField6.setText("");
jTextField7.setText("");

h[count].Resort = "" + jTextField1.getText ();
h[count].Airport = "" + jTextField2.getText ();
h[count].Accomodation = "" + jTextField3.getText ();
h[count].Departure_date = "" + jTextField4.getText ();
h[count].Length_stay = "" + jTextField5.getText ();
h[count].Price = "" + jTextField6.getText ();
h[count].Holiday_ref_no = "" + jTextField7.getText ();
}

public static void displayHolidays()
{
jLabel1.setText(h[count].Resort);
jLabel2.setText(h[count].Airport);
jLabel3.setText(h[count].Accomodation);
jLabel4.setText(h[count].Departure_date);
jLabel5.setText(h[count].Length_stay);
jLabel6.setText(h[count].Price);
jLabel7.setText(h[count].Holiday_ref_no);
}

public static void initialiseHolidays()
{
int count;
for(count=0;count<50;count++)
{
h[count] = new Holiday();
h[count].Resort = "XXX";
}
}

public static void AddHolidayDetails()
{
int index = 0;
while(!(h[index].Resort.equals("XXX"))&& index < 50)
{
index ++;
}
if(index==50)
{
jLabel8.setText("FULL UP - NO ROOM TO ADD");
}
else
{
EnterHoliday();
}
}

public static void ListHolidayDetails()
{
int count = 0;

ok i found out why, it was because i was clearing the text fields before it. that was having some effect. however my array is letting me add as many holidays as i want, it should however max out at 50


public static void AddHolidayDetails()
{
int index = 0;
while(!(h[index].Resort.equals("XXX"))&& index < 50)
{
index ++;
}
if(index==50)
{
jLabel8.setText("FULL UP - NO ROOM TO ADD");
}
else
{
EnterHoliday();
}
}
