Implement a recursive java method to find the sum of the first n int's in a java int array. max size 20.

Solution:

public class SumOfArray {

private int[] a;

private int n;

private int result;

   public int sumOfArray(int[] a,int n) {

     this.a = a;//Max size is 20

     n = a.length;

     if (n == 0)  // base case

     return a[n];

     else

         return a[n] + sumOfArray(a, n-1);

     return result;

  } // End SumOfArray method

} // End SumOfArray Class  

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
