I am very new to programming and I would like to ask for help please. i would like to know what the answer to the below is:
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]) = m[0,2] + m[1,1] + m[2,0]
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 [2x2], [3x3],[4x4], 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.”
