How to access linux command such as sed,awk from java

Question

I have been studying JNI (Java Native Interface) since last month.It is really interesting .I mean call Java functions from C and vice versa.Now I have an intention call linux command which I mentioned above like sed,awk from Java side.also I have a little bit knowledge about Sell Script in linux. please give me some hint how to do this.

Running separate binaries (as opposed to library functions) doesn't require the JNI. — Kevin, Mar 14 '14 at 15:08

You could use this java snippet to run a shell command:

Process process = Runtime.getRuntime().exec("echo This is a test"); //Start the process
process.waitFor(); //Wait for the process to terminate
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); //Get the output
