## Section 1 - Fundamentals

### Calculator

* **Description**

	* The purpose of this class is to create a simple calculator.

* **Methods to Complete**

	* `Double add(Double val1, Double val2)`

		* return the _sum_ of `val1` and `val2`

	* `Double subtract(Double val1, Double val2)`

		* return the _difference_ of `val1` and `val2`

	* `Double divide(Double val1, Double val2)`

		* return the _quotient_ of `val1` and `val2`

	* `Double squareRoute(Double value)`

		* return the _square root_ of `value`

	* `Double square(Double value)`

		* return the _square_ of `value`

	* `Double[] squareRoutes(Double[] values)`

		* return an array of `Double`, containing the square root of each of the elements in `values`.

	* `Double[] squares(Double[] values)`

		* return an array of `Double`, containing the square of each of the elements in `values`.

### StringUtils

* **Description**

	* The purpose of this class is to create utility `String` methods

* **Methods to Complete**

	* `String getMiddleCharacter(String string)`

		* return character at index `string.length()/2` as `String`.

	* `String capitalizeMiddleCharacter(String string)`

		* return near-identical `String` with character at index `string.length()/2` capitalized.

	* `String lowercaseMiddleCharacter(String string)`

		* return near-identical `String` with character at index `string.length()/2` lowercased.

	* `String invertCasing(String string)`

		* return near-identical `String` with each character's casing inverted: Capital letters become lowercase, lowercase letters become lowercase.

	* `Boolean hasDuplicateConsecutiveCharacters(String string)`

		* return `true` if `string` contains two identical characters in adjacent indices.

	* `Boolean removeDuplicateConsecutiveCharacters(String string)`

		* return near-identical `String` with each occurrence of duplicate-adjacent characters removed.

	* `Boolean isIsogram(String string)`

		* return `true` if each `Character` in `string` occurs exactly 1 time.





## Section 2 - Arrays

### ArrayUtils

* **Description**

	* The purpose of this class is to create a utility for manipulating arrays.

* **Methods to Complete**

	* `String getMiddleElement(String[] values)`

		* return the element at index `values.length/2`

	* `String[] removeMiddleElement(String[] values)`

		* return near-identical array with element at index `values.length/2` removed.

	* `String getLastElement(String[] values)`

		* return element at index `values.length-1`

	* `String[] removeLastElement(String[] values)`

		* return near-identical array with element at index `values.length-1` removed.





## Section 3 - Object Orientation

### Account

* **Description**

	* The purpose of this class is to create a model of an `Account`.

* **Methods to Complete**

	* `Long getId()`

	* `void setId(Long id)`

	

### BankAccount

* **Description**

	* The purpose of this class is to create a subclass of an `Account` which implements `Transactable`.

* **Methods to Complete**

	* `void setBalance(Double double)`

### Bank

* **Description**

	* The purpose of this class is to create an encapsulation of a `Collection` of `BankAccount` objects.

* **Methods to Complete**

	* `BankAccount removeBankAccountByIndex(Integer indexNumber)`

	* `void addBankAccount(BankAccount bankAccount)`

	* `Boolean containsBankAccount(BankAccount bankAccount)`

### Employee

* **Description**

	* The purpose of this class is to create an implementation of a `Worker` and `Transactable` which can `deposit`, `withdrawal`, and `getBalance`, of its composite `BankAccount`.

* **Methods to Complete**

	* `BankAccount getBankAccount()`

	* `void setBankAccount(BankAccount bankAccount)`

		

### Transactable

* **Description**

	* The purpose of this interface is to ensure a class can `deposit`, `withdrawal`, and `getBalance`.

* **Methods to Complete**

	* `void deposit(Double amountToIncreaseBy)`

	* `void withdrawal(Double amountToDecreaseBy)`

	* `Double getBalance()`

### Worker

* **Description**

	* The purpose of this interface is to ensure a class has `BankAccount`

* **Methods to Complete**

	* `BankAccount getBankAccount()`

	* `void setBankAccount(BankAccount bankAccount)`





## Section 4 - Collections

### Word Counter

* **Description**

	* The purpose of this class is to manage a mapping of `String` to `Integer`.

	* The class should be able to identify the number times a word has occurred in a given `String` array

		* A _word_ is a series of _characters_ delimited by _spaces_

* **Methods to Complete**

	* `Map getWordCountMap()`

	

### Food

* **Description**

	* The purpose of this class is to manage a list of `Spice` object.
