JAVA. Given two integer matrices A and B, you need toperform matrix addition (A + B). Both matrices
have N rows and M columns, N > 1 and M > 1. You need todivide both matrices (A and B) to four
equal (or close to equal) size of submatrices (A0,0, A0,1, A1,0,A1,1 and B0,0, B0,1, B1.0, B1.1) and each
submatrix has dimension of (N/2) x (M/2), or close to. You need tocreate four threads (processes)
each thread (process) perform a subset of addition on one pair ofthe submatrices. Example, thread
(process) 0 perform addition on A0,0 and B0,0, thread (process) 1perform addition on A0,1 and
