Write a program to do matrix multiplication in Java. Take the input from a file input.txt and write the output in out.txt file. In file input are matrices in this form

[1,2,3;4,5,6;][9,8;7,-6,50,61;] And output in out.txt should be in this form [173,179;371,368;] . The rows of matrix are separated by semicolon ' ; ' and columns are separated by comma ' , '

And if columns from first matrix are not equal rows second matrix, multiplication is not possible. Thank you for help. :)
