Code cleanup in netbeans

Solution 1:

Refactor > Inspect and Transform

Is there something similar to the Eclipse cleanup rules ((Preferences > Java > Code Style > Clean Up) in NetBeans?

In NetBeans 8.0, the powerful batch tool is Refactor > Inspect and Transform. See the tutorial page, Refactoring with Inspect and Transform in the NetBeans IDE Java Editor.

Individual tools are also available:

• Fixing imports
  For a single file, namespace, or project (depending on what's selected in Project window or has the focus): Source > Organize Imports (to sort and remove unused imports) or Source > Fix Imports (to sort, remove unused imports, and add missing imports). Or during every save: Tools > Options > Editor > On Save > Organize Imports.

• Removal of trailing spaces
  For a single file (place the carret in the code file): Source > Remove Trailing Spaces. Or during every save: Tools > Options > Editor > On Save > Remove Trailing Whitespace.

• Code Format
  For a single file, namespace, or project: Source > Format. (Customize the rules in Tools > Editor > Formatting). There is also a plugin called Jindent you can install (I have not used it myself). Or during every save: Tools > Options > Editor > On Save > Reformat.

By default, Netbeans will display hint icons next to problematic lines of code and in the scrollbar, allowing you to perform an automatic fix if desired. These can be configured via Tools > Options > Editor > Hints. Netbeans can search all problems in the project using Source > Inspect. Or, to reiterate, many of these problems can be batch fixed with Refactor > Inspect and Transform.

Solution 2:

The equivalent of Eclipse's "Code Cleanup" in NetBeans is "Format". It's under Source > Format, and the keyboard shortcut is Alt+Shift+F (on Windows). Unfortunately, unlike Eclipse, it doesn't seem like this can be configured in NetBeans.

Solution 3:

NetBeans 7.2 has Inspect & Transform refactoring to do this:

Solution 4:

For Netbeans use Ctrl+Shift+I to remove unused import from the file.
