Using JAVA, write array method that carry out the following tasks for an array of integers. Swap the first and the last elements in the array Remove the middle element if the array length is odd, or the middle two elements if the length is even. Return true if the array contains two adjacent duplicate elements Return the second largest element in the array Return the sum of the elements in the array Write a single test program in methods are called. Display the array before and after each call to demonstrated correct operation of the methods.
