GraphicsDevice monitors[]=GraphicsEnvironment.getScreenDevices(); 

Dimension screen_resolution[monitors.length];

for (int monitorID = 0; monitorID < monitors.length; monitorID++)
{
    screen_resolution[monitorID] = new Dimension(monitors[monitorID].getDisplyMode().getWidth(),monitors[monitorID].getDisplyMode().getHeight());
}
