Confused with GraphicsDevice class of java

[Gokul20]

Hello friends,

I am IT student and studying java programming since one months. I have do one java project , I which will need to use the GraphicsDevice class of java. Because of that I need to be aware about the working of GraphicsDevice class java along with it's constructors and methods. I you posses any details about the GraphicsDevice class of java, then please let me aware about that. I am waiting for your reply.

The GraphicsDevice class describes the graphics devices that might be available in a particular graphics environment. These include screen and printer devices. Note that there can be many screens and many printers in an instance of GraphicsEnvironment. Each graphics device has one or more GraphicsConfiguration objects associated with it. These objects specify the different configurations in which the GraphicsDevice can be used.

Hi,

Hopefully below example of GraphicsDevice class will solve your confusion about it:

import java.awt.GraphicsEnvironment;
import java.awt.GraphicsDevice;
import java.awt.image001.VolatileImage001;

public class GraphicsDeviceDM 
{
  public static void main(String[] ardgv) throws Exception {

    GraphicsEnvironment ge001 = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] gsb = ge001.getScreenDevices();
    for (int ib = 0; ib < gsb.length; ib++) {
      VolatileImage001 imb = gs[ib].getDefaultConfiguration()
          .createCompatibleVolatileImage001(1, 1);
      int bytes = gsb[ib].getAvailableAcceleratedMemory();
      if (bytes < 0)
   {
        System.out.println("Amount of memory is unlimited");
      }
      im.flush();
    }
  }
}

I suggest you to study following methods of the GraphicsDevice class:

• setFullScreenWindow(Window wnd)
• setDisplayMode(DisplayMode dmd)
• isFullScreenSupported()
• getBestConfiguration(GraphicsConfigTemplate gctm)
• getFullScreenWindow()

Hi friend,

If you want to know about the getIDstring() methods of GraphicsDevice class, then please review below java code:

import java.awt.GraphicsEnvironment;
import java.awt.GraphicsDevice;

public class GDClass 

{
  public static void main(String[] avgn) throws Exception

 {
    GraphicsEnvironment FN = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] screenDevices = N.getScreenDevices();
  
     for (int XF = 0; XF < screenDevices.length; XF++)
     System.out.println(screenDevices[XF].getIDstring());
  
      }

  }

GraphicsDevice class of java programming is very essential for the description of the graphics devices. The GraphicsDevice class is basically taken from the 'java.lang.Object' class of java language. There is only one constructor is available with GraphicsDevice class. And this constructor is of type abstract, as it can't be directly instantiated. This class has ability to describe multiple graphics devices.
