How can i convert quaternion to vector3 values ?

Hi Team, How can I convert my quaternion to vector3 values.
below is the reference link for the online converter. But how can I implement the same in java?

I took a look on the mentioned Repository for this Website and found this formula

var axis = [0, 0, 0];
var angle = 2 * Math.acos(q.w);
if (1 - (q.w * q.w) < 0.000001)
{
    axis[0] = q.x;
    axis[1] = q.y;
    axis[2] = q.z;
}
else
{
    // http://www.euclideanspace.com/maths/geometry/rotations/conversions/quaternionToAngle/
    var s = Math.sqrt(1 - (q.w * q.w));
    axis[0] = q.x / s;
    axis[1] = q.y / s;
    axis[2] = q.z / s;
}

I guess that is what you want? If so here is the blueprint, the conversion to java shouldn't be to hard :)

Thank you, I will try to integrate it with my code.
