simplest way to run command and get ouput:

Process p = Runtime.getRuntime().exec("ls");
p.waitFor();
Scanner s = new Scanner(p.getInputStream());
while (s.hasNextLine()) {
    String l = s.nextLine();
    System.out.println(l);
}

Pass the IP in command. I think this should work:

String sCommandString="sh /home/admin/ping.sh 10.12.12.26<Any IP>";

 Executing test.sh shellscript with passing param1 as parameter.Execute and wait for process to start and it will return int value 0 for successfully start of test.sh shellscript.

 Process process = null;
    try {
        int param1 =10;
        String[] command = {"sh", "-c", 'test.sh' + " " + param1};
        process = Runtime.getRuntime().exec(command);
        logger.debug("Process started for [param1 : " + param1 + "]);

        int i = process.waitFor();
        process.getOutputStream().close();

    } catch (Exception e) {
        logger.error("Error while creating process. Full stack trace is as follows ", e);
    } finally {
        try {
            if (process != null) {
                process.getInputStream().close();
            }
        } catch (Exception ex) {
            logger.error("Error while closing process. Full stack trace is as follows ", ex);
        }
    }

Why should the OP "try this"? A good answer will always have an explanation of what was done and why it was done that way, not only for the OP but for future visitors to SO that may find this question and be reading your answer.
