# ArraysGoneWild

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};
```
