 * calculate the average value of an double array - return an double `doubleAverageOfArray`
 * to test if an integer array contains a specific value, pass both array and value as arguments `containsValue`
 * reverse an array of integer values `reverseArray`
-* find the number of even and odd integers in a given array of integers `getOddEvensOfArray`, return an object of type
+* Make a method named `getOddEvensOfArray`
+* Method takes an argument of array of `Integer` objects
+* Method returns an object of type `OddEven` such that `OddEven` stores the number of `odds` and `evens` in the respective fields
 ```java
 public class OddEven{
     public int odds;
