Which is faster and uses less memory?
Answer is DATAREADER as it fetches only one row at a time whereas Dataset stores it as a table as whole.so it need much more network resourses.
Why do we use serialization?
Serialization allows the developer to save the state of an object and re-create it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions such as: Sending the object to a remote application by using a web service.
What is the benefit of serialization in Java?
Serialization allows us to transfer objects through a network by converting it into a byte stream. It also helps in preserving the state of the object. Deserialization requires less time to create an object than an actual object created from a class. hence serialization saves time.
What is advantage of serialization in Java?
Why do we need serialization in Java?
In Java, we create several objects that live and die accordingly, and every object will certainly die when the JVM dies. Well, serialization allows us to convert the state of an object into a byte stream, which then can be saved into a file on the local disk or sent over the network to any other machine.
When should I use serialization in Java?
Serialization in Java allows us to convert an Object to stream that we can send over the network or save it as file or store in DB for later usage. Deserialization is the process of converting Object stream to actual Java Object to be used in our program.
What is serialization used for?
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
