      Here we are using the format that initializes a 2D array when the array is defined. In this case let’s make it so maze[0][0] is the upper left corner and maze[9][9] is the lower right corner. Because of the way 2D array contents are specified in C++, the first index refers to the row (y coordinate) and the second index

      An array object (or simply array) contains a collection of elements of the same type, each of which is indexed (i.e., identified) by a number. A variable of type array contains a reference to an array object. To use an array in Java we have to: 1. declare a variable of type array that allows us to refer to an array object;
