How to Create Flowchart from java source code in Eclipse [closed]

I would like to create the flowchart or sequence diagram from my java source code.
Is there any plug-in which can help me do that?

What is a Java flowchart?

A flowchart is a diagrammatic representation of an algorithm. A flowchart can be helpful for both writing programs and explaining the program to others.

ObjectAid is a free UML tool which can creates sequence diagrams. Another commercial tool to create sequence diagrams from existing code is Architexa. I use Architexa very often at my daily work.
