First: do not excuse for something you perfectly know it is wrong. Instead do it right from the start and put it into the right place.

Second: how did you intend to interact with the c program?

I used the exec method of Runtime, but with this i am able to pass parameters to c program but i am not able to interact with it.


Example:

Runtime rt=new Runtime();
Process p=rt.getRuntime().exec("./hello praff");

In this i am able to send parameters to c program.


but if i want to read something in c using scanf during the execution it's not working.

Of course it doesn't. Where should it get the input from? Your program does not provide any kind of input stream to the "hello" process.
