Fancy-Integer-ArrayList

This project was to practice writing code in Java and applying overloading concept.

INSTRUCTIONS

In this assignment, you will implement a class called CustomIntegerArrayList. This class represents a fancy ArrayList that stores integers and supports additional operations not included in Java's built-in ArrayList methods.

For example, the CustomIntegerArrayList class has a “splice” method which removes a specified number of elements from the CustomIntegerArrayList, starting at a given index. For a CustomIntegerArrayList that includes: 1, 2, 3, 4, and 5, calling splice(1, 2) will remove 2 items starting at index 1. This will remove 2 and 3 (the 2nd and 3rd items).

The CustomIntegerArrayList class has 2 different (overloaded) constructors. (Remember, an overloaded constructor is a constructor that has the same name, but a different number, type, or sequence of parameters, as another constructor in the class.) Having 2 different constructors means you can create an instance of the CustomIntegerArrayList class in 2 different ways, depending on which constructor you call.

Internally, the CustomIntegerArrayList class uses a private ArrayList variable named “arr” to store its integer elements. The “CustomIntegerArrayList()” constructor initializes the ArrayList variable “arr” as an empty ArrayList and the “CustomIntegerArrayList(ArrayList arr)” constructor initializes the ArrayList variable “arr” with the elements in the given ArrayList.

There are 8 (mostly overloaded) methods that need to be implemented in the CustomIntegerArrayList class. (Again, an overloaded method is a method that has the same name, but a different number, type, or sequence of parameters, as another method in the same class.)

• getArrayList() - Returns the elements.
• get(int index) - Returns the element at the specified index from the elements.
• add(int element) - Appends the given element to the end of the elements.
• add(int index, int element) - Inserts the given element at the specified index.
• remove(int index) - Removes the element at the specified index.
• remove(int num, int element) - Removes the specified number of the given element from all elements.
• splice(int index, int num) - Removes the specified number of elements from all elements, starting at the given index.
• splice(int index, int num, int[] otherArray) - Removes the specified number of elements from all elements, starting at the given index, and inserts new elements in the given array at the given index.
