Not Displying to the Text Area
 
I am trying to out put to a TextArea but it is not working. I believe I am missing something. I am using NetBeans and it will run on the output box of NetBeans but not in the GUI (TextArea). Any ideas?

Re: Not Displying to the Text Area
 
if you replace for example
System.out.print("Report of wages to date:" + newline + newline);

with

jTextArea1.setText("Report of wages to date:" + newline + newline);

you will have the desired.
