Describe the difference between a "Static" and "Non-Static" method

- A static method can be accessed directly from a class, while a non-static method is accessed from the class instance. In other words we can say, static methods are accessed by their class names which encapsulates them, while non-static methods are accessed by object reference. Static methods cannot access instance methods or variables within a class.
- Static methods are one per class while non-static methods are one per instance.
- Static methods cannot use non-static methods and variables without object instantiation while non-static methods can use static methods directly.
