Static method vs instance method

What is a static method? Static methods, much like class methods, are methods that are bound to a class rather than its object . They do not require a class instance creation. So, they are not dependent on the state of the object.

When you declare a variable or a method as static, it belongs to the class, rather than a specific instance . This means that only one instance of a static member exists, even if you create multiple objects of the class, or if you don’t create any.

A static method has two main purposes: For utility or helper methods that don’t require any object state . Since there is no need to access instance variables, having static methods eliminates the need for the caller to instantiate the object just to call the method.
