Given a square matrix m[3x3], create a java code to calculate

Programming Assignment solution

Given a square matrix m[3x3], create a java code to calculate the value of its SECONDARY Diagonal See example below Hint:

In order to better understand the concepts Involved in this exercises, research the terms “square matrix" and “secondary diagonal of a matrix" using your favourite search engine.
Example given matrix m[3x3] shown below:
(0,0) (0,1) (0,2)      10    12       11
(1,0) (1,1) (1,2)       9     8         31
(2,0) (2,1) (2,2)       2     16       24
Secondary Diagonal (generic m[3x3] = m0,2) + mt[l , 1] + m[2,1]
Secondary Diagonal (as in the example above) 11 + 8 + 2 = 21
Note 1: Your java code MUST be GENERIC to calculate the secondary diagonal of ANY square matrix t2x2), etc. (Use a constant in your code to set
the values of numberOfRows and numberOfColumns of your matrix_
Note 2: Your matrix m may be hardcoded (no need of user interaction)
Note 3: In case numberOfRows and numberOfColumns ar differents, your program must display the following message: •This IS not a square matrix."
