Need help with the code. Java is preferred. Please and thank you

Calculate P(O|Lambda) Where O = {H, H, T} And Lambda = Implement the Forward algorithm in MATLAB or Java. Your task is to write code for the following prototype: Forward(A, B, Pi, Obv) Returns P(Obv|Lambda) You may optionally use an initialization method/function Create your own 3 observation "Obv" vector and calculate P(O|Lambda) for this vector. Create a "Obv" vector of at least 7 elements. Test your Forward algorithm implementation using the 3 observation vectors.
