Implementation of Bezier Curves Algorithm for 6 Points in Java?

Question

Java

Guys, save, you need to implement the algorithm for drawing Bezier curves for 3,4,5 and 6 points. We really need your help!

Only the implementation came to mind in this way: P(1) = P0*t^2 + P1*2*t*(1-t) + P2*(1-t)^2, where we substitute the previously declared coordinates and the value of t. We do this for every point. And so for each straight line, I tried to implement it, but without success.
