Determine if the following statements is true or false.
Screen shot shows the text's arraycollection and sortedarraycollection
With the text's array-based collection implementation, the set of stored elements is scattered about the array.
The text's sorted array-based collection implementation stores elements in the lowest possible indices of the array.
When comparing two objects using the equals method inherited from the Object class, what is actually compared is the contents of the objects.
