Introduction to Record Classes in Java
What are Record Classes?
Record classes in Java are a special kind of class designed to hold immutable data. They significantly reduce the boilerplate code typically associated with creating simple data-carrying classes. Introduced as a preview feature in Java 14 and 15, and officially standardized in Java 16, record classes provide a concise way to declare classes that are primarily used to store data.
Key Features
Immutable Data: Record classes are designed for immutability. The fields in a record are final and cannot be changed after the object is created.
Automatic Generation of Methods: When you declare a record, Java automatically generates several useful methods, including:
A canonical constructor
equals()
hashCode()
toString()
Getter methods (named after the fields)
