Solution for the given question are as follows -

Code :

class ArrayPalindrome {
// checkPalindrome is a Recursive function check array is Palindrome or Not
static int checkPalindrome(String arr[], int start, int end)
{
   if (start >= end) {
       return 1;
   }
   if (arr[start] == arr[end]) {
       return checkPalindrome(arr, start + 1, end - 1);
   }
   else {
       return 0;
   }
}
   public static void main (String[] args) {
String arr[] = { "dog","dog","cat","cat" };
   // String arr[] = { "a","tree","tree","a" };
   // call to checkPalindrome() function
int result = checkPalindrome(arr, 0, arr.length - 1);
   if (result == 1)
       System.out.print( "Array Is Palindrome");
   else
       System.out.println( "Array Is Not Palindrome");
   }
}
