Q1) Write a method to multiply two matrices. The header of the method is as follows: With java public static int[] Il multiplyMatrix(int[] [] a, int[] [] b) To multiply matrix a by matrix b, the number of columns in a must be the same as the number of rows in b, and the two matrices must have elements of the same or compatible types. Let c be the result of the multiplication, and a, b, and care denoted as follows: au 014 012 d22 013 023 015 a 25 021 a24 031 d32 033 034 035 bil b2b3b14 bis b21 222 223 224 225 b31b32 b33b34 634 541 642 643 644 644 bi b52 553 554 b54 042 043 044 045 041 051 052 053 054 055/ cu C12 C13 C14 C15 C21 C22 C23 C24 C25 C35 C31 C32 C33 C34 C42 C43 C44 C45 C41 C51 C52 C53 C54 C55 where Cij = aj1 x bij x + a2 x baj x + aj3 x bz; x + aj4 x b4; x + ais x bsj
