Homework: sum of 2 arrays

---

In this assignment, we will be writing a Java method called arraySum() that adds two double-type arrays and returns the sum of them.

The arraySum(a, b) method will add the elements a[i] + b[i] together and creates a result array of the sum.

For example, if the input arrays are:

double[] a = {1, 2}; double[] b = {1, 1};

the arrayAdd(a,b) call will return an array with values {2, 3}

And if the input arrays are:

double[] c = {2, 3, 4, 5}; double[] d = {-1, -1, -1, -1};

the arrayAdd(c,d) call will return an array with values {1, 2, 3, 4}

Use the program below to complete the assignment:

public class myProg { public static void main(String[] args) { double[] a = {1, 2}; double[] b = {1, 1}; double[] c = {2, 3, 4, 5}; double[] d = {-1, -1, -1, -1}; double[] x; x = arraySum(a, b); System.out.println( Arrays.toString(a) + " + " + Arrays.toString(b) + " = " + Arrays.toString(x) ); x = arraySum(c, d); System.out.println( Arrays.toString(c) + " + " + Arrays.toString(d) + " = " + Arrays.toString(x) ); } // Write the method arraySum() here }
