Java OpenGL Syntax

Question

i am new here and have a little problem. I included OpenGl into eclipse and tried to run a little test program and everything is working fine as it should, but i have a problem with the syntax.

Here is a little example :

GL11.glEnable(GL11.GL_DEPTH_TEST);
GL11.glMatrixMode(GL11.GL_PROJECTION);
GL11.glLoadIdentity();
GLU.gluPerspective(45, (float)Display.getWidth()/(float)Display.getHeight(), 0.3f,1000f);
GL11.glMatrixMode(GL11.GL_MODELVIEW);

As far as i remember i didnt have to call the GL version everytime and should look like this :

glEnable(GL_DEPTH_TEST);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
GLU.gluPerspective(45, (float)Display.getWidth()/(float)Display.getHeight(), 0.3f, 1000f);
glMatrixMode(GL_MODELVIEW);

I havnt found any answer out there because for everyone it seems to work from scratch. I start to believe that i did a mistake while including opengl into eclipse but i did it like i did it back at university.

java build path

Hopefully someone knows what i can do or not do :D

I tried following tutorials on youtube and they all use the second codeblock and even if i follow the same libraries it doesnt work for me while it works in the tutorial ??? I tried different build paths and didnt change anything. I tried to change the library version but didnt do anything either.

To reference static methods with qualifying them with the class name, eg glEnable(x) instead of GL11.glEnable(x), you must import the static methods, either individually or all of them:

import static fully.qualified.path.GL11.*;
