Write a Java program (non-GUI preferred) to demonstrate the Singleton pattern.

The key parts of the singleton pattern are:

  • A private static variable to store the single instance called the singleton
  • A public static method for callers to get a reference to the instance
  • A private constructor so no callers can instantiate the object directly

Using these key parts, write a Java program that will allow a user of the program to assign only one runner to each of the 8 lanes of running track in a field.

Include a brief documentation (in the code or in a separate document) to explain the input (if any), processing and output of the program.

Submit your assignment using the Assignment Files tab above.

Instructor’s Note: This can be a pretty challenging assignment.  The key here, and throughout this course, is to understand the concepts.  Thus, I will occassionally include sample programs.  You are welcome to use Antinques.java and adapt it to this assignment.

Please submit functional JAVA code with a section for me to enter my name and date in the documentation section of the program. Attached is a sample program provided by the instructor.
