JAVAAAAAAA help me write this method!!!!!!

/**
             * This randomly selects, with the Random number generator passed as a parameter,
             * one of elements (array of int) in the neighbors list. If the size of neighbors is 0 (empty)
             * then null is returned. If neighbors contains 1 element then that element is returned. The
             * randGen parameter is only used to select 1 element from a neighbors list containing
             * more than 1 element. If neighbors or randGen is null then an error message is
             * printed to System.err and null is returned.
             *
             * @param neighbors A list of potential neighbors to choose from.
             * @param randGen The random number generator used throughout the simulation.
             * @return A int[] containing the coordinates of a creatures move or null as specified above.
             */
            public static int[] chooseMove(ArrayList<int[]> neighbors, Random randGen) {
                //TODO Milestone 2
                return null; //change in Milestone 2
            }

Explanation / Answer

public static int[] chooseMove(ArrayList neighbors, Random randGen) { //If neighbors is empty, or randGen is null, return null if (neighbors == null || neighbors.isEmpty() || randGen == null) { System.err.print("null"); return null; } //If neighbors has a single element, return that element if (neighbors.size() == 1) { return neighbors.get(0); } //randomly return an element return neighbors.get(randGen.nextInt() % neighbors.size()); }
