Is there an error in this Java book? or am I missing something? (DisplayMode)

Question

The following code is written the exact same way as in a Java book I am reading

package main;

 import java.awt.Color;
 import java.awt.DisplayMode;
 import java         


        

Answer 1

DisplayMode has to do with Java "Full Screen Exclusive Mode" functions, which are documented here:

• http://docs.oracle.com/javase/tutorial/extra/fullscreen/displaymode.html

• http://docs.oracle.com/javase/7/docs/api/java/awt/DisplayMode.html

I would encourage you to try some of the sample programs here:

• http://docs.oracle.com/javase/tutorial/extra/fullscreen/example.html

The bottom line is:

1) not all OS's or display devices are necessarily supported by this API

2) All combinations of arbitrary DisplayMode settings aren't necessarily supported if the device itself doesn't support them
