1 Individual: Singleton Pattern Program

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

The key parts of the singleton pattern

  • 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.
