JAVA! I am struggling with arrays and would like to see this problem worked out.

First Part: Calculate the inverse of this matrix

double a[][]={

{2,3},

{4,5}

};

// calculate the inverse of this matrix and store the answer in 2D array namely b as double.

Second Part: Given a matrix of 2 rows & 3 columns that looks like this:

int a[][]={

{1,2,3},

{4,5,6}

};

Convert this matrix to 3 rows and 2 columns that look like this:

{ {1,4},

{2,5},

{3,6} } // the matrix is rotated

Start a 2D array of 3 rows and 2 columns and loop to store the answer in it and print it out.
