Study Notes

Static Members in Java

Static members belong to a class, not an instance of the class.
The main method is declared as static in Java so that it can be invoked by the Java Virtual Machine (JVM) without creating an instance of the class.

Static Methods

A static method in Java has the main characteristic of being bound to a class rather than an instance of the class.
Static methods can be invoked without creating an instance of the class.

'this' Keyword in Static Methods

A static method in Java cannot use 'this' to refer to instance variables because 'this' refers to the instance of the class, and static methods are not associated with an instance.

Static Members Inheritance

A static member is inherited by a subclass but not overridden, because it belongs to the class itself, not to an instance of the class.
