What is Singleton Pattern in Java - How to achieve this?

In this video, I have explained What is Singleton Pattern in Java - How to achieve this?

The Singleton pattern in Java is a design pattern that restricts the instantiation of a class to one "single" instance. This is useful when exactly one object is needed to coordinate actions across the system. The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance.

Thank you for the video! I am migrating a shell script to Java, and I want to implement logging. If I want to implement, some custom functions for the Logger class, does it make sense to make a CustomLogger using a Singleton design pattern?

Naveen, why do we need two null check for the browser? Why isn't one null check enough?

Thanks Naveen if we go for eager initialisation instead of lazy ie creating instance before access. We will not require synchronised block correct me if wrong
