Singleton Pattern Program
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.
