Re: Edited code does not run correctly
Thanks this was the issue, i did update the original question as i am now getting errors, but it seems to have vanished
Re: Edited code does not run correctly
There is a variable with a null value when line 14 is executed.java.lang.NullPointerException
at java.text.AttributedString.<init>(AttributedString .java:127)
at PrintText.<init>(PrintText.java:14)
Look at line 14 and find the variable with the null value. Then backtrack in the code to see why that variable does not have a valid, non-null value.
Please edit your post and wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

Re: Edited code does not run correctly
Thank you, the code at line 14 was in the wrong place, i have now put this into the print method, however i am now getting this error

Re: Edited code does not run correctly
Now look at line 109 the same way you looked at line 14 in the previous error.Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at java.text.AttributedString.<init>(AttributedString .java:127)
at PrintText.print(PrintText.java:109)
