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
