Your line nos seem 1 out from the error messages, but
studno1 = new JLabel(text[9]); is the line in question
text = new String [9]; is the size of "text"
so the valid array indexes for text are 0..8

[rowen17]

i've tried changing the size of text to 10. unfortunately, a new error occur and I can't seem to identify the problem. here's the error message

Exception in thread "main" java.lang.NullPointerException
at accountinfo.launch2(Main.java:98)
at accountinfo.main(Main.java:143)
Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)

[adams161]

you have these 4 lines:

pn1 = new JPanel();
pn2 = new JPanel();
pn3 = new JPanel();
pn4 = new JPanel();

but i see 8 panels or up to pn8. 4 are null so maybe that is the null pointer exception. I really hate to see variables like pn1 through pn8. that's where you use arrays.

oh my god! I can't believe i missed that.. thanks Adam161 and JamesCherrill. cheers! :)

[rowen17]

and thanks for the suggestion about using arrays. :)
