I normally use eclipse and for me is a good IDE.

Eclipse comes with a built-in Java formatter that is not compliance with the Java convention and for this reason I create a Java formatter available on github, click here to get the latest version.

In short my Java formatter:

• indent 4 spaces
• use space instead of the tab character
• split every row @ 80 characters per line
• format the Javadoc
• don't format comment
• try to be compliance with the Java and Google conventions
• pass verify of checkstyle

Instructions:

1. Clone git repository or download the Java formatter

2. Start eclipse

3. Click on Window → Preferences
   

4. Search "formatter" in filter text input bar and then select Java → Code Style → Formatter
   

5. Click on "Import..." button and select the Java formatter, previously downloaded

6. Verify that "Java and Google Conventions - pirola.org" is the Active profile and click on "Apply"

7. Click and "OK"

That's all!!!

You can format your code in different ways:

• All classes

  1. Click with the right mouse button on src/main/java, if you use maven, or on root project an select "Source" → "Format"
     

• Single class

  1. Select all your Java code class- Shortcut: Right Ctrl + A
     

  2. Format the code - Shortcut: Right Ctrl + Right Shift + F
     

Happy coding ;)
