A StringBag is a container that holds String objects. Consider the following starter code for a StringBag class.

public class StringBag {

// the array to hold the data

private String [] bag;

// the number of elements being held (also the next index where a new

// String can be put).

private int count;

public StringBag(int length) {

bag = new String[length];

count = 0;

}

}

[2 points] Write a function that returns the number of items that have been added to the StringBag object.

Write your test case for this method.

public void testSize()

// Replace this test with your code

Write your method.

public int size()

{

// Replace this test with your code

}
