Tutorial on Serialization in Java - Part2

Transient keyword:

When we have a class which implements Serializable interface, that means its eligible for getting serialized but we want few fields not to get serialized then we can place the transient keyword before their declarations to tell the serialization mechanism that the field should not be saved along with the rest of that object's state. Then those transient fields will not be serialized. That means their values will not be saved into bytestream while serialization and when deserialization, those transient fields will be stored back into the object with their default values.

For example,

What is serialization and how its performed?

Serialization is a mechanism through which we can save the state of an object by converting the object into a byte stream.

Serialized object (byte stream) can be transferred over network, persisted or saved into file/database.

We can deserialize the Serialized object (byte stream) and gets back the original object.

Let’s try to write a Java' program to serialize an object.
