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:
For a full description of record classes, refer to the Java Language Specification.
Example:
class Point {
private final double x;
private final double y;
Point(double x, double y) {
this.x = x;
this.y = y;
}
double getX() {
return x;
}
double getY() {
return y;
}
}
After the quick-fix is applied:
record Point(int x, int y) {
}
Enable the Suggest renaming accessor methods option to rename getX()
/isX()
accessors to x()
automatically.
Use the If members become more accessible option to specify what to do when conversion will make members more accessible:
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 only reports if the language level of the project or module is 16 or higher.
