How do you get the screen width in java?

Question

Does anyone know how you would get the screen width in java? I read something about some toolkit method but I\'m not quite sure what that is.

Thanks, Andrew

Here are the two methods I use, which account for multiple monitors and task-bar insets. If you don't need the two methods separately, you can, of course, avoid getting the graphics config twice.

static public Rectangle getScreenBounds(Window wnd) {
    Rectangle                           sb;
    Insets                              si=getScreenInsets(wnd);

    if(wnd==null) { 
        sb=GraphicsEnvironment
           .getLocalGraphicsEnvironment()
           .getDefaultScreenDevice()
           .getDefaultConfiguration()
           .getBounds(); 
        }
    else { 
        sb=wnd
           .getGraphicsConfiguration()
           .getBounds(); 
        }

    sb.x     +=si.left;
    sb.y     +=si.top;
    sb.width -=si.left+si.right;
    sb.height-=si.top+si.bottom;
    return sb;
    }

static public Insets getScreenInsets(Window wnd) {
    Insets                              si;

    if(wnd==null) { 
        si=Toolkit.getDefaultToolkit().getScreenInsets(GraphicsEnvironment
           .getLocalGraphicsEnvironment()
           .getDefaultScreenDevice()
           .getDefaultConfiguration()); 
        }
    else { 
        si=wnd.getToolkit().getScreenInsets(wnd.getGraphicsConfiguration()); 
        }
    return si;
    }
