I'll try to look at your code later. You need to make some alterations:

Java class names begin upper case, otherwise they look like method or variable names. You have a class called 'guestName' which takes in its ctor a String[] called 'guestName1'. That's confused and confusing.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I'll look at it later if i can. Also get rid of the 'magic numbers' in your code. How could the likes of
if(keycode == 119)

Open in new window

ever be seen as readable?? You will forget within a few days what that's meant to do

Change this:

       row = new Vector(3);
        for (int i = 0; i < guest_no; i++)
        {
            
            row.addElement(guestName[i][0]);
            row.addElement(guestName[i][1]);
            row.addElement(guestName[i][2]);
            data.addElement(row);
        }

Open in new window


into this

        for (int i = 0; i < guest_no; i++)
        {
            row = new Vector(3);  // <<<<<<< this line should be inside the loop
            row.addElement(guestName[i][0]);
            row.addElement(guestName[i][1]);
            row.addElement(guestName[i][2]);
            data.addElement(row);
        }

Open in new window


and your problem will be gone.

Explanation:
With your code the result of 'data' after the loop was:
data = { {A, 0, B, C, 1, D }, {A, 0, B, C, 1, D } }
with the corrected code it is:
data = { {A, 0, B }, { C, 1, D } }

Oh, and - as CEHJ - remarked:

for readability reasons, you'd better replace

if (evt.getKeyCode() == 119)

Open in new window

by
if (evt.getKeyCode() == KeyEvent.VK_F8)

Open in new window


and 'guestName1' by 'parameters'

Success!
