The installation wizard would appear.

Use the default settings and finish the installation and run Visual Paradigm.

Use the 30 day trial version.

Using Visual Paradigm

Select Tools  Code - Reverse Java Code

Right Click JavaRound-trip  Reverse “Java-Roundtrip” New Class Diagram

Select No

Select Show fully Qualified owner

This generates the class diagram of the entire application

You can generate the class diagram of single class along with its related classes as well. Right Click the specified class and select generate Class Diagram

Sequence Diagram :-
Tools  Code  Instant Reverse Java to Sequence Diagram

Select the source folder of the project. Then click Next. Select the operation for the class for which you need to generate the sequence diagram.

Click Finish

Draw use-case diagram for the application. It cant be generated automatically.
