Java array. Please keep it basic and simple.

public class PQ06
{
   /**
    *  1. Write the method maxEnd3()
    *
    *  You are given an array of int of any length.
    *  Your method should figure out which is the
    *  larger of the first and last elements in the
    *  array, and then new array of length 3,
    *  with every element set to that value. Return
    *  the new array. Do not change your original
    *  array.
    *
    *  Some examples:
    *      maxEnd3({1, 2, 3}) returns {3, 3, 3}
    *      maxEnd3({11, 5, 9}) returns {11, 11, 11}
    *      maxEnd3({2, 11, 3}) returns {3, 3, 3}.
    *
    *  @param nums an array of int (any length)
    *  @return an array (length 3) containing the maximum element.

   /**
    *  2. Write the method averageOdds()
    *
    *  Start with a positive int array of named nums. Return the
    *  average of all the odd numbers in the array.
    *  A number (n) is odd if n % 2 == 1. If there are no
    *  odd numbers in the array, return -1.
    *
    *  Some examples:
    *       averageOdds([1, 2, 3]) returns 2.0
    *       averageOdds([2, 4]) returns -1.0
    *       averageOdds([2, 3, 4]) returns 3.0
    *
    *  @param nums an array of int (any length)
    *  @return the average of the odd numbers in the array.
