Static and singleton difference

Question

Accepted Answer

Static keyword is used to declare a variable or method that belongs to the class itself, while singleton pattern is used to ensure a class has only one instance and provides a global point of access to it.

Static keyword is used to declare variables or methods that belong to the class itself, not to instances of the class.
Singleton pattern is a design pattern that restricts the instantiation of a class to one object.
Static variables are shared among all instances of a class, while singleton instances are unique.
Static methods can be called without creating an instance of the class, while singleton instances are accessed through a static method that returns the single instance.
Example: A static variable in a class can be used to keep track of the number of instances created, while a singleton class can be used to manage a connection to a database.
