The inspection can be useful if you need to focus on modeling immutable data rather than extensible behavior. Automatic implementation of data-driven methods, such as equals and accessors, helps to get rid of boilerplate.
Note that not every class can be a record. Here are some of the restrictions:
To get a full list of the restrictions, refer to the Oracle documentation.
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;
}
}
This record will be converted to:
record Point(int x, int y) {
}
This inspection only reports if the language level of the project or module is 14 preview or higher.
