No Arguments:
try {
        // Execute a command without arguments
        String command = "ls";
        Process child = Runtime.getRuntime().exec(command);
        // Execute a command with an argument
        command = "ls /tmp";
        child = Runtime.getRuntime().exec(command);
    } catch (IOException e) {
    }With Arguments:
try {
        // Execute a command with an argument that contains a space
        String[] commands = new String[]{"grep", "hello world", "/tmp/f.txt"};
        commands = new String[]{"grep", "hello world", "c:\\Documents and Settings\\f.txt"};
        Process child = Runtime.getRuntime().exec(commands);
    } catch (IOException e) {
    }
