What are non-static methods?

What is static and non static method?

A static method can access only static members and can not access non-static members. A non-static method can access both static as well as non-static members. Static method uses complie time binding or early binding. Non-static method uses run time binding or dynamic binding.

When would you use a non static method?

What is the static method?

A static method (or static function) is a method defined as a member of an object but is accessible directly from an API object’s constructor, rather than from an object instance created via the constructor.
