Problem with the Logic

**sudh** · March 29th, 2011, 07:01 AM

Hi there,
I have just 6 months familiarity with JAVA so excuse me if I am being foolish sometimes. ..
My objective is to create an application in Java which should be able to create a flow chart of a Java program once its source code is given as input to the application. It should also be able to generate a basic class hierarchy or functional hierarchy (If there is one) by reading the source code of the application. Now my problem is that I am researching on this since two weeks but didn't get anything significant.......My approach to do this would be

1. Parse the Java Program..extract as much info as I can
2. Use tis info to generate the flow chart and all

now problem with the first is I need to write grammars to parse the java program...and it may complicate the project....so Can you people suggest any other solution or a more elegant approach....

To generate gramars I am thinking of using Antlr is it the right choice or Is there something better??...and even better can anyone guide me on ow to write full fledged grammar to parse a Java Program So that the stated objectives can be achieved???...
hanks in advance.....plz help

Well, this looks something more related to Artificial Intelligence. You should try to solve it step by step. I'll recommend you to have a notebook and pencil and a piece of code and try to make flowchart with your mind. Now, start reading and understanding your mind as deep as you can.
How you will see the code?
From where will you start reading the code?
How will you behave against each line of code/logic?
And many other small things, as smaller as you can to simplify your logic into generic one.

I don't know what do you mean by grammer, but i think you mean, giving terms to some logic... Am i right??
Anyways, this is the solution that can lead you to solve your problem.
Don't think of API's in the very start, instead first create a logic and then look over different API's that will help you to accomplish your task in the all possible, efficient manner.
