Removing roll from camera matrix

I have a camera class which is just this:

import org.joml.*;

public class Camera {
    public Matrix4f viewMatrix = new Matrix4f().setTranslation(new Vector3f(100, 200, 100));

    public void rotate(float x, float y) {
        viewMatrix.rotateXYZ(x, y, 0);
    }
    public void move(float x, float y, float z) {
        viewMatrix.translate(x, y, z);
    }
}

import org.joml.*;

public class Camera {
    public Matrix4f viewMatrix = new Matrix4f().setTranslation(new Vector3f(100, 200, 100));

    public void rotate(float x, float y) {
        viewMatrix.rotateXYZ(x, y, 0);
    }
    public void move(float x, float y, float z) {
        viewMatrix.translate(x, y, z);
    }
}

and it works, but I want to eliminate the roll from the matrix somehow.

Figuring out path to resources in built jar

Im currently doing this to read my shader files:

Utils.readFile("src/main/resources/assets/base/shaders/scene.vert")

Utils.readFile("src/main/resources/assets/base/shaders/scene.vert")

and it works when just testing in intellij, but if i build the jar it no longer works as the src/main/resources part of the path doesnt exist. Any solutions?

Get progress of int between two other ints.

I have three integers, min, max, and value. Value is always between min and max, but I need to figure out how to get a double that represents how "far along" the value is from min to max. For example: Min: 0 Max: 100 Value: 69 would return 0.69 as it is 69% between 0 and 100.
I just need help on the math required for this.
