The preferred way to create processes in recent versions of Java is to use the ProcessBuilder class, which makes this very simple:

ProcessBuilder pb = new ProcessBuilder("./test.sh", "kstc-proc");
// set the working directory here for clarity, as you've used a relative path
pb.directory("foo");
Process proc = pb.start();

But if you do want to/need to use Runtime.exec for whatever reason, there are overloaded versions of that method that allow the arguments to be specified explicitly:

Process proc = Runtime.getRuntime().exec(new String[]{"./test.sh", "kstc-proc"});

Here is something very simple you can try

public class JavaRunCommandExample {

    public static void main(String[] args) {

        Runtime r = Runtime.getRuntime();
        Process p = null;
        String cmd[] = {"./test.sh","argument1"};

        try {
            p = r.exec(cmd);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
