A is question about java

public class Q1Furthest { /** * Given an array of integers and a special value target, * return the value in the array that is numerically furthest from * target. If the array contains two different values equally * close to target, return the larger value. If the array is * empty, return target. * * @param in An array of integers * @param target a target value to search for in the array * @return the value in the array that is numerically furthest from * target, returning the larger of equally close values, and * returning target if the array * has no entries. */ public static int findFurthest(int[] in, int target) { // FIXME complete this method return Integer.MAX_VALUE; } }
