Java – matrices does not work in OpenGL

I am trying to create an orthogonal matrix and an appropriate model and view matrix to view a simple triangle just to test the matrix I've been looking at a blank screen. I don't know what happened I'm using lwjgl. For vertices and matrices, I'm using a library called joml

Main class (unique class):

Vertex shader:

Clip shader:

Solution
