Write a Java program named RandomNumbers that creates a single-dimensional array of int of size 20 and initialize its elements with 20 random integer numbers (their range must be between 1 and 100 inclusive. Write statements in your program to display the array elements, and how many odd and even numbers are there in the array. For example, if the random numbers were stored in the array are: 83 48 89 66 40 94 31 31 12 45 45 87 10 24 78 2 28 31 52 46 Then the program should display: The random numbers are: 83 48 89 66 40 94 31 31 12 45 45 87 10 24 78 2 28 31 52 46 There are 8 odd numbers There are 12 even numbers An element in the array is a peak (max or min) if the elements before and after that element are greater than the element itself (min) or the elements before and after that element are less than the element (max).
