Static and non static methods:

Static method: A static method is one that belongs to a class instead of an instance of a class and this method can be called without an instance or the object of the class. If a static keyword is not mentioned before the class name then it is by default a non-static class. A static method belongs to the class rather than the object of a class. A static method can be invoked without the need for creating an instance of a class. A static method can access static data members and can change their value of it. Restrictions for the Static Method Advantages of static Keyword Saves Memory: Faster Access: Great for Utility Methods: Good for Constants: Keeps Code Organized: Runs Automatically When the Class Loads: Reduces Object Dependency: The static method cannot use non-static data members or call a non-static method directly. this and super keyword cannot be used in static context.[TBD] Non Static Method Non-static members are specific to each instance of a class, as they are tied to objects created from the class. Non-static members have memory allocated separately for each instance of the class. Each object has its own copy of non-static members Non-static members are accessed using an object reference followed by the member name Example: Ref: https://www.tpointtech.com/static-keyword-in-java https://www.scaler.com/topics/static-and-non-static-in-java/

Non Static Method
Non-static members are specific to each instance of a class, as they are tied to objects created from the class.
Non-static members have memory allocated separately for each instance of the class. Each object has its own copy of non-static members
Non-static members are accessed using an object reference followed by the member name
