Start by looking at, reading the comments in,
and then compiling and running the program
in TestIntArraySort.java in this diretory.
Then read the following and carry on ...

The files in this directory illustrate how
the Comparable and Comparator interfaces
can be used to sort, in various ways, an
array of (quite simple) Employee objects.
The employees are sorted by name, by id
number, and by age.

An important takeaway from what is shown
here is that (now, in Java 8) "lambda
functions" can be used to avoid the rather
cumbersome use of several Comparator objects
to sort the array of Employees several different
ways, which is how it would have been done prior
to Java 8.

It is also very important to know how to sort
things in various ways, since much of what 
most computer software does is either sorting
a collection of something in some way, or
searching for something in a collection of
some kind.

Now study the remaining files in this directory
in this order:
- TestEmployeeArraySortByComparators.java along with
Employee.java and the three Employee*Comparator.java files.
- TestEmployeeArraySortByLambdas.java
