Executing C program object code using java in linux

Question

I was developing a simple C code generator in java in Linux and i wanted my java program to automatically compile and run the generated C code,i.e. the .out file. Though i have been able to compile it successfully I am not able to run the compiled object code. Can anyone please write the code to suggest how to execute the C code using the java program.

The script file contains code for compiling. Process p=Runtime.getRuntime().exec("/home/jerisalan/Documents/workspace/CodeGenerator/script.sh /home/jerisalan/Documents/workspace/CodeGenerator/output.c"); Process r=Runtime.getRuntime().exec("/home/jerisalan/Documents/workspace/CodeGenerator/./output.out"); — Jeris

If you're successfully creating the .out file, then you should be able to run it with one of the Runtime#exec functions:

Runtime.getRuntime().exec("./a.out");

...or (more control) via the stuff in the Process class. The Process class stuff lets you do things like control the input and output (via streams).

@jerisalan: About 150 things, you'll have to show your code. It's very hard to help with coding problem without code.
