Reboot.java

public class Reboot extends Activity implements View.OnClickListener {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        ((ImageButton) findViewById(R.id.restartButton))
                .setOnClickListener(this);
    }

    public void onClick(View v) {
        try {
            Process proc = Runtime.getRuntime().exec(
                    new String[] { "su", "-c", "reboot" });
            proc.waitFor();
        } catch (Exception ex) {
            Log.i("Reboot Code", "Could not reboot", ex);
        }

        //This method also i did, kindy un comment this code and then check
        // try {
        // Runtime.getRuntime().exec(
        // new String[] { "/system/bin/su", "-c", "reboot now" });

        // e.printStackTrace();
        // }
    }

You cannot call su on a production device if the device is not rooted. Rooted means that you have more access/permissions on the device (it can be a security risk). If you did not setup the device for root, then it is NOT rooted, therefore you cannot su.
