[Solved] SOLVED:Singleton pattern.

Write a Java program 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.
