![]() But the real impact of using the Record class can only be realized when you actually use it – as it is said: the proof of the pudding is in the eating. Developers can absolutely go without it and stick to the old ways of living. After all, it is a convenient class specifically designed to be used as a data carrier that defies the verbosity of the POJO class declaration, as per Java language specifications. The introduction of the keyword record that implicitly uses class added another layer of convenience to it. Java’s Record class can have many innovative use cases, apart from being just a data carrier. Invoice = new Invoice(String.valueOf(i+1), amt) Return getId() = person.getId() & int hashCode() If (o = null || getClass() != o.getClass()) return false Here is a code example on creating such a class in Java: package org.example The record class redefines data carrier classes to another level both in terms of convenience and efficiency.Ī simple POJO class we often use as a data carrier may contain a lot of boilerplate code. In fact, developers can manage everything without the record classes as we have been doing so long. This class aggregates – or holds – a group of values without having to write boilerplate code and acts as an efficient carrier of data objects. These downsides led to the introduction of a special type of class called record. A simple carrier class becomes heavy with a lot of unnecessary code due to the verbose nature of the Java language. Now, writing such a data class, even if it may be a simple POJO, includes a lot of boilerplate code, such as private fields, constructors, getter and setter methods, hashCode(), equals(), and toString() methods. Note that the sole purpose of the object is to carry the data from the server to the client. The server responds back with the object of the class to the client. Since everything is an object in Java, there must be some class that carries the data. For instance, suppose, a client requests some data from the server such as an id and name of a person and the server responds back with the appropriate data. Similarly, programmers often write classes for the sole purpose of carrying data. ![]() While working on Java projects, we, as developers, often write service classes, security classes, or any other basic classes.

Record is a special purpose class in Java that is designed to provide an efficient and easy way for programmers to carry aggregate data. ![]() We may make money when you click on links to our partners. content and product recommendations are editorially independent. ![]()
