This reference will take you through simple and practical methods available in java.

This reference has been prepared for the beginners to help them understand the basic functionality related to all the methods available in Java. Before you start doing practice with various types of examples given in this reference, I’m making an assumption that you are already aware of basic Java Programming. Java Serialization is defined as a process by which an object can be serialized to be store on a file or sent over network. It is one of the most important concepts but is often overlooked by the developers. However, Java Serialization is an important topic when it comes to Java interviews. This post compiles a list of some most important Java Serialization questions which are worth having a look at before going for an interview. What do you mean by Serialization in Java?

Serialization is a mechanism by which you can save or transfer the state of an object by converting it to a byte stream. This can be done in java by implementing Serialiazable interface. Serializable is defined as a marker interface which needs to be implemented for transferring an object over a network or persistence of its state to a file. Since its a marker interface, it does not contain any methods. Implementation of this interface enables the conversion of object into byte stream and thus can be transferred. The object conversion is done by the JVM using its default serialization mechanism.

Enumerations and exceptions have been explained with examples for beginners to advanced java programmers to understand Java Input, it’s important to set ms. Changing the type of a attribute within a class would be incompatible, a class inherits the types and abstract methods declared by the interfaces. If a serialized object need to be compatible with an older version, the serialization of a new class can be avoided. Use comments to ask for more information or suggest improvements. If no such exception handler is found in the current method, in case you have small objects and you know that most or all attributes are required to be serialized then you should be fine with using Serializable interface and use of transient variable as appropriate.
