What is transient variable in Java? Serialization Example

What is a transient variable in Java?

transient variable in Java is a variable whose value is not serialized during Serialization and which is initialized by its default value during deserialization, for example for object transient variable it would be null. This behavior can be customized by using a custom Serialized form or by using the Externalizable interface. A transient variable is used to prevent any object from being serialized and you can make any variable transient by using the transient keyword. You cannot make a local variable transient through and it's only the member variables which can be transient. 

What is default Serialization in Java? Serializable and Externalizable Interface Explanation

What is Serialization in Java
Serialization in Java is a process to persist any Java Object's state into a File System or convert them into a byte stream to transfer over the network to another JVM or program. Serialization in Java is done by JVM by employing the default Serialization process which persists all of the Object's state except the transient variable and a static variable. How Serialization works in Java is another popular Java Serialization interview question, well It's easy to make any Java class Serializable, the class needs to implements java.io.Serializable interface, and JVM will automatically serialize its instance when passed over to java.io.ObjectOutputStream using writeObject(). 

Difference between transient vs volatile variable or modifier in Java

transient vs volatile modifier in Java
What is the difference between transient and volatile variables or modifiers in Java is one of the most common Serialization Interview Questions in Java. Though volatile variables are not related to Serialization at all, this question is mostly asked in conjunction with other Serialization questions. Both transient and volatile modifiers are completely different from each other. In fact, this question is as popular as Serializable vs Externalizable in Java. The main difference between transient vs volatile variables is that transient variables are not serialized during the Serialization process in Java while volatile variables are used to provide alternative synchronization in Java. 

Difference between Serializable vs Externalizable in Java - Interview Question

What is the difference between Serializable and Externalizable in Java is famous core Java interview questions and for some of them its one of those difficult Java question, which no one wants to see in Java interview. I was in that category until I read Effective Java and explored How Serialization works in Java and find out more about the Serialization process. What makes Serialization questions tricky is, Serialization as a persistence mechanism is not very popular. Many programmers prefer databases, memory-mapped files, or simple text files over Serialization. But Serialization has a distinguished advantage over these mechanisms.

13 Java Serialization Interview Questions with Answers for 3 to 5 Years Experienced

There is no doubt that Java is vast and there are some Java topics which many Java developers rarely explore in work but they are important from a Java interview point of view. Serialization is one of them which is rarely used in practice but quite popular during Java interviews. It's also one of the difficult topics to master and that's why I am going to share some frequently asked Java Serialization interview questions in this article.  I don't know why people ask so many questions from Serialization if not everyone uses it but I have always seen some questions from Java realization. These are also the toughest and confusing questions to answer and more likely cannot be answered by an average Java developer.

Java Serialization Example and Tutorial for Beginners [Guide]

Serializing an object in Java is never easy and many Java developers often get confused. There are so many rules, interfaces to implement, and then always a chance of data loss or an error during the Serialization or deserialization process.  In the past, I have posted a detailed guide of Serliazing Object in Java which is very liked by my readers and they asked for more information like what should Java developers remember while using the Serializable and Externalizable interface in Java.
