I have managed to get a cube rendered in OpenGL using a VBO. My next goal is actually creating a for loop to create multiple cubes. I’m stuck on this part though, do I put this code:

GL11.glEnableClientState(GL11.GL_VERTEX_ARRAY);
    ARBVertexBufferObject.glBindBufferARB(ARBVertexBufferObject.GL_ARRAY_BUFFER_ARB, vertexBufferID);
    GL11.glVertexPointer(3, GL11.GL_FLOAT, 0, 0);
    GL11.glDrawArrays(GL11.GL_QUADS, 0, 24);
    GL11.glDisableClientState(GL11.GL_VERTEX_ARRAY);

Into a for loop? Wouldn’t I have to use some sort of glPopMatrix command along with a translate function? I barely understand how to create one cube in a VBO, so sorry if its obvious whats wrong.

    You can use the following way:

    GL11.glEnableClientState(GL11.GL_VERTEX_ARRAY);
ARBVertexBufferObject.glBindBufferARB(ARBVertexBufferObject.GL_ARRAY_BUFFER_ARB, vertexBufferID);
GL11.glVertexPointer(3, GL11.GL_FLOAT, 0, 0);

for (int i = 0; i < cubeCount; i++) {
  GL11.glPushMatrix();
  // do translation/rotation for cube no i
  GL11.glDrawArrays(GL11.GL_QUADS, 0, 24);
  GL11.glPopMatrix();
}

GL11.glDisableClientState(GL11.GL_VERTEX_ARRAY);

    Please note that the glPushMatrix/glPopMatrix way is deprecated in newer openGl versions. For you it should work because you are using GL11.
