Abstract: In todays world, every aspect of business is driven by IT. Jobs in IT Industry are never static. They are most dynamic and people keep on switching from one industry to other. So this result in lack of continuity of same people working on same project tills its completion and hence at any time there is need to add new people to the project. So the most important thing for the new comers to any project is to understand the flow of entire project. Reverse engineering is the study of an applications code and behaviour, in order to better understand the system and its design. There are many existing tools that will assist the developer with this undertaking, such as Rational Rose®, jGRASP®, and Eclipse®.So there is necessity to provide a framework which would convert the given code into UML diagrams. So, our project idea is to develop a tool which would convert the given code into UML diagrams. Although, there are certain tools available in the market as given above which do this work, but all these tools are paid application and other which are open source lack behind in certain aspects which would be overcome by our tool.
