We know that arrays are different types, as usual one dimensional array, two dimensional array, three and multi (mxn) dimensional arrays. In two dimensional arrays we need 2x2 array. A 2x2 matrix is a rectangular often square array of numbers having 2 columns and 2 rows, or expressions which can be evaluated to numbers. The dimensions m x n refer to the number of rows (m) and columns (n) respectively. We can declare the one dimensional array as: int[] myArray = {0,1,2,3}; and two dimensional array looks like this: int[][] myArray = { {0,1,2,3}, {3,2,1,0}, {3,5,6,1}, {3,8,3,4} }; this array size is 4X4. Here in our program we are using 2X2 array only. Let us take two arrays named as A(2X2) and B(2X2), then add these two arrays. The resultant array(matrix) named as C(2X2). A general formula shown below notice that the indices match for the elements that combine, and that matrix addition and subtraction is commutative; e.g (A + B = B + A...
The best way to learn Java programming is by practicing examples. The page contains examples on basic concepts of Java. You are advised to take the references from these examples and try them on your own.
