Best way to understand new codebase




 I'm wondering if there are any aids/tools/plugins/something inbuilt that help a newbie easily understand the existing code.

For example,understanding what is going on in badly formatted java classes having huge no of lines, and too many methods etc.

Hello Phaneendra,

actually many IDEA features are related to navigation in a code and may help to understand the existing code. E.g. you can use 'Go to implementation' to see how a method is implemented, use 'Find Usages' to discover how it's used, 'File Structure' to view top-level members of a java class, etc, see our help for details. If java classes are badly formatted you can use 'Reformat Code' action to reformat them automatically.
