Hi my name is Paul and not only am I new to Java, I am also new to programming all out. So I am sorry if I'm asking a very elementary question.
I am trying to figure out how to write a class for a 3d cube. I can not figure out how and where you're suppose to write the code for the vertices and nodes. This is what I have written and it's completely wrong so far.

package shapes;
public class CubeMain extends Object {
private int nodes;
private int edges;
public CubeMain() {
int nodes = x,y,z,w,h,d;
nodes = x,y,z,
x, y+h, z+d,
x+w, y, z,
x+w, y, z+d,
x+w, y+h, z,
x+w, y+h, z+d;

This is not an appropriate forum for this type of question. This is a basic question about how to program in Java but this forum is for asking questions about how to use Eclipse. Even when I think of other forums such as StackOverflow and JavaRanch I imagine people answering questions there will expect you to learn at least some basics of Java so you can ask a question that isn't of the form, Can you teach me Java.

As you are new to programming, it's very easy to understand your mistake, so let me try and explain what's going on.

By analogy, you've stumbled into a power tools seminar and you're asking a table saw vendor "How do I build a 2-story colonial home with aluminum siding?". The table saw vendor doesn't know, and is confused why you're asking him.

Eclipse is a tool, like a hammer or saw, that can be used to do many things, including write programs, including writing programs in java, and including writing programs in java that do graphics.

Your question is about using java, probably with OpenGL or LWJGL, to write a program to draw a cube.

Since your question has to do with java programming, it's not an eclipse question. Beyond that it's a library-specific question (how do I put a cube on the screen) so it's not really a java question either. You need to find a forum (such as at or which will have people more likely to have experience aligned with your question.

Allow me to further recommend searching "opengl java tutorial" in Google and Youtube for more information.

Good luck, sir!
