Note: Maintains a capacity value for maximum number of items that can be stored, and a size value for the number of valid or viable data items in the array

Implement the followings in ArrayClass:

Fields

	private int	arrayCapacity
	private int	arraySize
	private static int	DEFAULT_CAPACITY
	static int	FAILED_ACCESS
	private int[]	localArray
Constructors
Constructor and Description
ArrayClass() Default constructor, initializes array to default capacity (10)
ArrayClass(ArrayClass copied) Copy constructor, initializes array to size and capacity of copied array, then copies only the elements up to the given size
ArrayClass(int capacity) Initializing constructor, initializes array to specified capacity
ArrayClass(int capacity, int size, int fillValue) Initializing constructor, initializes array to specified capacity, size to specified value, then fills all elements with specified size value

Method Summary

All MethodsInstance MethodsConcrete Methods
Modifier and Type	Method and Description
int	accessItemAt(int accessIndex) Accesses item in array at specified index if index within array size bounds
boolean	appendItem(int newValue) Appends item to end of array, if array is not full, e.g., no more values can be added
void	clear() Clears array of all valid values by setting array size to zero, values remain in array but are not accessible
int	getCurrentCapacity() Description: Gets current capacity of array
int	getCurrentSize() Description: Gets current size of array
boolean	insertItemAt(int insertIndex, int newValue) Description: Inserts item to array at specified index if array is not full, e.g., no more values can be added
boolean	isEmpty() Tests for size of array equal to zero, no valid values stored in array
boolean	isFull() Tests for size of array equal to capacity, no more values can be added
int	removeItemAt(int removeIndex) Description: Removes item from array at specified index if index within array size bounds
boolean	resize(int newCapacity) Description: Resets array capacity, copies current size and current size number of elements
