error message when executing

[oltbaba]

i'm new here!
i already installed the lwjgl jar files and everything else into the lib/ext directory.
now i wrote this class.

=================================
package monitor_test;


import org.lwjgl.DisplayMode;
import org.lwjgl.Display;
import org.lwjgl.input.Keyboard;
import org.lwjgl.opengl.Window;
import org.lwjgl.opengl.GL11;

public class Game {
   
   public static void main(String[] args) {
       try {
           int mode = -1;
           DisplayMode[] modes = Display.getAvailableDisplayModes();
           System.out.println("Found " + modes.length + " display modes");
           
       }
       catch(Exception e) {
           System.out.println(e.toString());
       }

   }
=================================

compiling is no further problem but when i execute it i get the following error message:

Exception in thread "main"

When using the package statement at the start of a class, you must also place the java file in a directory that mirrors it.

Example Java file:
package test.monitor;

public class Test1 {
}


Well the file Test1.java must be placed in a directory structure that mirrors the package statement so:
C:/$AppSrc/test/monitor/Test1.java

It looks to me like this is your problem.
