NetBeans – Reformat text

The NetBeans IDE has a great shortcut for reformatting sourcecode.  Simply hit ⌃⇧F (ctrl shift f), and all the sourcecode in the current file will be reformatted.  This is a great feature, and I only stumbled upon it through a StackOverflow search.

Before reformatting. This is how the code looked on StackOverflow

After running the algorithm. Note how much more readable it is

The other time it’s useful is when working on a project where someone is using very large tab settings (e.g. 8 spaces per tab instead of 4).  This can make it very difficult to read.  By invoking this command, you’ll put the code into a much more readable format.
