Non Access Modifiers in Java

Access modifiers provide a mechanism for Access Control and different access modifiers can be used to achieve different accessibility. But Non Access Modifiers have nothing to do with accessibility. But it is used to determine specific characteristics of class/variable/methods etc. Below are the 7 Non Access Modifiers available in Java.

String Builder

A String Builder is like a String but can be modified. String has the drawback that once created it can not be modified. To overcome that problem String Buffer and String builder can be used.

Serialization in Java

Java object serialization is used to persist Java objects to a file, database, network, process or any other system. Serialization flattens objects into an ordered, or serialized stream of bytes. The ordered stream of bytes can then be read at a later time, or in another environment, to recreate the original objects.

Class Inheritance in Java is used to build new Classes from existing Classes. The inheritance relationship is transitive: if Class x extends Class …

Java Method Override

A class inheriting the method from its superclass has the option to override it. The benefit of overriding is the ability to define behavior specific to a particular class. In the case of a concrete subclass, it is forced to implement all methods defined in abstract class if no other superclass implemented it in the hierarchy. Overriding sometimes referred …
