![]() ![]() ![]() In the below program code, you will use the transient keyword to two data members and display all the data members’ values.Īs you can see, the transient data members return the default value, which is 0 for integers and null for strings. If you don’t want any data member to get serialized, you have to add the transient keyword. The transient is a reserved keyword in Java. But since the serialization will have no impact on the static data, its value would be changeable before de-serializing it. In the example below, you will use a static data member and serialize the object. Serialization ignores the static data members in Java. ![]() Serialization in Java with Static Data Member This means that if you want to serialize an object with reference to another class, all the references must be serializable, or else it will throw NotSerializableException. In the below code, the Student object will not be serialized as the Address class does not implement the Serializable interface, and it has tried to use the reference from the Address class to serialize the Student class. Serialization in Java With Aggregation (Has-A Relationship) Let’s look at that point in action with this Java serialization example in inheritance. Serialization in Java With Inheritance (Is-A Relationship)Īs mentioned in the points to note section, when a parent class implements the Serializable interface, the child classes do not have to do so. By default, the String and all wrapper classes implement the Serializable interface.The serialization process only saves non-static data members, but not static or transient data members.The child class doesn’t have to implement the Serializable interface, if the parent class does.All the fields of a class must be serializable otherwise, use the transient keyword (more about it later).You can serialize an object only by implementing the serializable interface.Serialization is a marker interface with no method or data member.These are the conditions and points to remember while using serialization in Java. Some other key points need to be highlighted before you proceed further in the article. To serialize an object, there are a few conditions to be met. Points to Note About Serialization in Java? Used for marshaling (traveling the state of an object on the network).Serialization offers a plethora of benefits. What are the Advantages of Serialization? The best part about these mechanisms is that both are JVM-independent, meaning you serialize on one JVM and de-serialize on another. Usually used in Hibernate, JMS, JPA, and EJB, serialization in Java helps transport the code from one JVM to another and then de-serialize it there.ĭeserialization is the exact opposite process of serialization where the byte data type stream is converted back to an object in the memory. The byte stream has all the information about the object. Serialization in Java is the concept of representing an object’s state as a byte stream. It will also explore how to serialize an object, and how to serialize using different Java concepts, with examples. This serialization in Java article will shed light on the mechanism of serialization, and its benefits. ![]()
