In records, a canonical constructor is generated automatically. We can redefine the canonical constructor if we need to perform some operations on data before initializing the fields. We can also define compact and custom constructors (no argument and multi argument).

The methods like equals(), hashcode(), and toString() are generated automatically. We can override these methods if needed.

In a record, it is possible to create our own custom instance method to perform calculations. But the instance variables cannot be declared in a record.
