Question

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

Answer 1

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
