What is Singleton Class in Java | Singleton Design Pattern Part 1

For code click here:

The singleton pattern is implemented by creating a class with a method that creates a new instance of the class if one does not exist.

If an instance already exists, it simply returns a reference to that object.

To make sure that the object cannot be instantiated any other way, the constructor is made private.

thanks for clarifying singleton class. you are a genius. Respect!!! nobody explained it like you did here

[rjlifeandtech]

Nice explanation. Here I found that, Inside Abc class, "static Abc obj = new Abc();" is defaulted to a public statement, so, inside the main method, java will allow accessing directly static obj object. eg. "Abc obj1 = Abc.obj;", so getInstance() method is never needed to use. To fix this, we can mention like "private static Abc obj = new Abc();" and getInstance() method can be used now.

It would so good if you gave it with a real life example.Syntax is easy to learn but the implementation in programming daily life problems is so important here.
But the video and the explanation is amazing.

Firstly, it was hard for me to understand the concept of Singleton pattern even after watching 4-5 videos, but your one video was more clear and was able to understand within few minutes. Thanks for the good stuff!

We can also remove the getInstace method and can directly call the object by writing (Abc obj1 = Abc.obj) in main method
