Inverse of a matrix in java

Question

I would like to calculate an inverse of matrix in java. Are there any already existing packages which calculate inverse of matrix. I found similar question, but the answers in the questions are not so strongly recommending to use anyof the packages. Even i could not follow the method they are using. I have a large matrix of 10000s of rows and columns. I would like to calculate inverse of it.
