Exceptions headache

Troubleshooting General Help

hi guys



from the first day I downloaded latest jme engine and updated it to the latest available plugins … still i have problems with it



first, the GUI its self have some bar in the most-right bottom corner named: Opening SceneViewer, which is stuck at 14% and whatever i do it wont disappear.



second, i wanted to make my first game landscape (terrain), so i copied and pasted the code in this link:

https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_terrain





and tried to compile and run it, and that’s what i got:



run:

java.lang.ExceptionInInitializerError

Caused by: java.lang.RuntimeException: Uncompilable source code - class HelloTerrain is public, should be declared in a file named HelloTerrain.java

at jme3test.helloworld.HelloTerrain.(Main.java:19)

Exception in thread “main” Java Result: 1

BUILD SUCCESSFUL (total time: 4 seconds)





actually not a single code did run on jmonkey engine on my pc , i always get exceptions.



any help or clues are really appreciated



thanks

I'm not sure how that error can be any clearer. This is a basic Java learning issue and not really a JME one.
