+a series of problems to prove your array knowledge.
+you use the information in the docs folder only, NO GOOGLE on this lab.
+
+### For each problem.
+
+For each of these problems, you need to write the method itself, and two tests for each method. 
+If the method is named `sumValuesOfArray`, you should write two test methods:
+* test1sumValuesOfArray
+* test2sumValuesOfArray
+
+### Problem list
+
+Write a method in the Arraz class for each of these:
+
+* sum values of an array of integers `sumValuesOfArray`
+* sum values of an array of doubles `sumDoublesOfArray`
+* calculate the average value of an integer array - return an integer `averageOfArray`
+* 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
+```java
+public class OddEven{
+    public int odds;
+    public int evens;
+}
+```
+
+* find the index of an array element, pass both array and value as arguments `findIndexOf`
+* copy an array by iterating the array `copyArrayByInterator`
+* copy an array by looping thru the array `copyArrayByLoop`
+* remove a specific element from an array `removeElementFromArray`
+* insert an element into an array a specific position `insertIntoArrayAt`
+* find the maximum and minimum value of an array `findMaxMinOfArray` return a 
+```java
+public class MaxMin{
+    public int max;
+    public int min;
+}
+```
+* remove duplicate elements from an array, return new array `removeDupesFromArray` (make it an array of Integers)
+* find the second largest element in an array of Doubles `find2ndLargestValueFromArray`
+
+* convert an array to ArrayList `makeMeAnArrayListFromArray`
+* convert an ArrayList to an array `makeMeAnArrayFromArrayList`
+* test the equality of two arrays `check2ArraysForEqual`
+* compute the average value of an array of integers except the largest and smallest values (be thinking
+of code re-use for this one) `averageArrayWithoutMaxMin`
+* check if an array of integers contains two specified elements: 65 and 77, returns a boolean `arrayHas65and77`
+* check if the sum of all the 10's in the array is exactly 30. Return false if the condition does not satisfy, otherwise true. `theTotalofTensIs30`
+* find smallest and second smallest elements of a given array
+
+* copy an array of integers, reverse it, and return it. `makeMeACopyPlease`
+* remove the last element from an array of integers, return a copy `removeLastItemAndCopy`
+* remove the first element from an array of integers, return a copy `removeFirstItemAndCopy`
+* insert a new element at the start of an array, return a copy `insertAtStartAndCopy`
+* insert a new element at the end of an array, return a copy `insertAtEndAndCopy`
+
+* separate even and odd numbers of an given array of integers. Put all even numbers first, and then odd numbers `sortArrayIntoEvensThenOdds`
+
+If you need an array of ints use this one.
+```java
+int[] spiffyHandyIntArray = new int[] {4,5,102,6,-7,12,-32,92,8};
+```
+
+
+If you need an array of Doubles use this one.
+```java
+Double[] spiffyHandyDoubleArray = new Double[] {1.0, 0.5, 3.6, 38.4, 17.3, 62.0, 9.0, 3.375, 0, 3.14159};
+```
