Java arrays: multidimensional declaration and final references
Java supports multidimensional arrays.
The focus is on two-dimensional arrays.
Two-dimensional arrays are declared and allocated with two pairs of square brackets.
The two dimensions are specified as the array sizes.
Example: int matrix[][] = new int[10][20];
The keyword final prevents changing the array reference.
The contents of a final array can still be modified.

"Java supports multidimensional arrays, though we’ll only focus on 2-dimensional arrays. To declare and allocate 2-dimensional arrays, we use two square brackets with two specified dimensions.\n\nint matrix[][] = new int[10][20];\n\nThe use of the keyword final only prevents us from changing the array reference, not modifying its contents."
