Data Structures and Algorithms
with Object-Oriented Design Patterns in Java 
Program 
declares the TwoWayMergeSorter class.
The TwoWayMergeSorter class extends the AbstractSorter class
defined in Program .
A single field, tempArray, is declared.
This field is an array of Comparable objects.
Since merge operations cannot be done in place,
a second, temporary array is needed.
The tempArray field keeps track of that array.
Program: TwoWayMergeSorter fields.
