1. Create a new package named cst8132.sarray 2.

Calls default super constructor. o Capacityout0fBoundsException (String s) Initial constructor. Passes the specified String message to the super class constructor " 3. StringArray class, in the cst8132.sarray package, with the following members o Import any Exception classes as required. Do not use any "catch-all import statements. o private int capacity // The current capacity of the array " How many Strings could my array contain? private int size //The current size of the array o How many String objects are populated in my Array? o private String[] stringArray // The current String array o StringArray() Default constructor, Constructs an empty StringArray with an initial capacity of 10 " o StringArray (int initialCapacity) throws IllegalArgumentException Initial constructor.
