The output window of NetBeans can contain very long lines of text. Normally we get a horizontal scrollbar and we need to scroll to see the complete line.

Or we can right-click in the output window and select Wrap text. A nice feature is the addition of little arrows at the end of the lines that are wrapped. See the following screenshot for an example:
