I have created the Attendance Utility. Here in the module contains Short Break, Lunch break ,Day Attendance  etc etc.

Suppose the candidates goes for short breaks he needs to click on the button and the moment he click on the login screen will come and the screen should be locked.

When one enters the password the screen should be unlocked and so on.

Is there any method in java that can lock the screen.

Application is Windows Based using Swings.

Runtime r = Runtime.getRuntime();
Process p = r.exec("rundll32.exe user32.dll, LockWorkStation");
p.waitFor();
BufferedReader b = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";

while ((line = b.readLine()) != null) {
  System.out.println(line);
}
