What is the use of GraphicsEnvironment class?

[Jagruti23]

Hi All,

I need you help to sort out my query related to the GraphicsEnvironment class of java programming language. This GraphicsEnvironment class sounds very complicated to understand. Even I don't have any idea about it's methods and properties also. I wonder if anybody let me know something about the GraphicsEnvironment class of the java with a suitable java code . I would appreciate your help.

The GraphicsEnvironment class describes the collection of GraphicsDevice objects and Font objects available to a Java(tm) application on a particular platform. The resources in this GraphicsEnvironment might be local or on a remote machine. GraphicsDevice objects can be screens, printers or image buffers and are the destination of Graphics2D drawing methods. Each GraphicsDevice has a number of GraphicsConfiguration objects associated with it.

Below I have given the java example, which will depict you the use of GraphicsEnvironment class:

import java.awt.GraphicsEnvironment;
import java.awt.Font;

public class GPEClass 

{
  public static void main(String[] argms) throws Exception 
{
    Font[] fonts1  = GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
    for (int iy = 0; iy < fonts.length; iy++) 
    {
      System.out.print(fonts1[iy].getFontName() + " : ");
      System.out.print(fonts1[iy].getFamily() + " : ");
      System.out.print(fonts1[iy].getName());
      System.out.println();
    }
  }
}

Hello friend,

You should be aware about following methods of GraphicsEnvironment class before accessing it's properties:

• getAvailableFontFamilyNames(Locale lcl)
• isHeadlessInstance()
• createGraphics(BufferedImage BFimg)
• getMaximumWindowBounds()
• getCenterPoint()

Example of GraphicsEnvironment class:

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

public class GraphicENClass

 {
  public static void main(String[] args) {
    GraphicsEnvironment gez = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice defaultScreen = gez.getDefaultScreenDevice();
    GraphicsConfiguration[] configurations = defaultScreen.getConfigurations();

    System.out.println("Default screen device: " + defaultScreen.getIDstring());
    for (int iz = 0; iz < configurations.length; iz++) {
 
     System.out.println("  Configuration " + (iz + 1));
 
     System.out.println("  " + configurations[iz].getColorModel());
    }
  }
}

A GraphicsEnvironment class is used for description of the objects of GraphicsDevice class. you can use only one constructor of GraphicsEnvironment class. The java package from which this class is hired is 'java.lang.Object'. You can use the constructor of GraphicsEnvironment class, but cannot instantiated because of it's abstract type behavior. This java class is used where the functionality of GraphicsDevice class is not applicable.
