Java-check if control key is being pressed

Question

I have a Java function in which I want to test if the control key is being held down. How can I do that?

Edit: I am using swing for gui.

Answer 1

I found one solution which solves my problem: I declare a global variable

boolean controlStatus=false;

Then in the event for keyPressed on the jTextField:

if(evt.getKeyCode()==KeyEvent.VK_CONTROL)
      controlStatus=true;

In the event for keyReleased:

if(evt.getKeyCode()==KeyEvent.VK_CONTROL)
      controlStatus=false;

Then I can access the global variable to check if the control key is being held down.
