IN JAVA

I am mostly interested in how to do this using what is described in the circle while also having it output in the correct ORDER.

Implement a method/function that produces running sum runningSum2DArray (int[] [] array, int dir) across rows (left to right or right to left) or columns (top to bottom or bottom to top) Input to the method: A 4x4 two dimensional int array and an integer (1, 2, 3 or 4 for left, right, up, down respectively). Output: The modified array after producing the running sums according to the direction. For example: If the input to the method is the same as the earlier array, and if the direction is 2 (right), the output array would be printed as: ArrayList> list, int dir) that performs the same functionality.
