Using OpenGL C reference with Java/LWJGL?

[dime]

Hi, I'm trying to learn newer OpenGL (3.3 or above).  I found a nice tutorial :

http://www.opengl-tutorial.org/

I can create a basic window, but getting stuck on lesson 2: /tutorial-2-the-first-triangle/

Are there any guidelines on converting this to lwjgl ?  I know this exists in LWJGL, but just having troubles on exactly 'how' to convert it.

What would be the process of converting this example into Java/LWJGL?

init

// An array of 3 vectors which represents 3 vertices
static const GLfloat g_vertex_buffer_data[] = {
   -1.0f, -1.0f, 0.0f,
   1.0f, -1.0f, 0.0f,
   0.0f,  1.0f, 0.0f,
};

// This will identify our vertex buffer
GLuint vertexbuffer;
 
// Generate 1 buffer, put the resulting identifier in vertexbuffer
glGenBuffers(1, &vertexbuffer);
 
// The following commands will talk about our 'vertexbuffer' buffer
glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer);
 
// Give our vertices to OpenGL.
glBufferData(GL_ARRAY_BUFFER, sizeof(g_vertex_buffer_data), g_vertex_buffer_data, GL_STATIC_DRAW);

render

// 1rst attribute buffer : vertices
glEnableVertexAttribArray(0);
glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer);
glVertexAttribPointer(
   0,                  // attribute 0. No particular reason for 0, but must match the layout in the shader.
   3,                  // size
   GL_FLOAT,           // type
   GL_FALSE,           // normalized?
   0,                  // stride
   (void*)0            // array buffer offset
);
 
// Draw the triangle !
glDrawArrays(GL_TRIANGLES, 0, 3); // Starting from vertex 0; 3 vertices total -> 1 triangle
