Class can be record class
Reports classes that can be converted record classes.
Record classes focus on modeling immutable data rather than extensible behavior. Automatic implicit implementation of data-driven methods, such as
equals() and accessors, helps to reduce boilerplate code.
Note that not every class can be a record class. Here are some of the restrictions:
The class must be a top-level class and must have no subclasses.
All non-static fields in the class must be final.
Initializers, generic constructors, and native methods must not be present.
For a full description of record classes, refer to the Java Language Specification.
After the quick-fix is applied:
Enable the Suggest renaming accessor methods option to rename
isX() accessors to
Use the If members become more accessible option to specify what to do when conversion will make members more accessible:
Choose Do not suggest conversion option to not convert when members would become more accessible.
Choose Show conflicts view option to show the affected members and ask to continue. In batch mode conversion will not be suggested.
Choose Convert silently option to increase accessibility silently when needed.
Use the Suppress conversion if class is annotated by list to exclude classes from conversion when annotated by annotations matching the specified patterns.
This inspection depends on the Java feature 'Records' which is available since Java 16.
