Record pattern can be used

Reports patterns that can be replaced with record patterns.

Example:

record Point(int x, int y) {} static void printSum(Object obj) { if (obj instanceof Point p) { int x = p.x(); int y = p.y(); System.out.println(x + y); } }

After the quick-fix is applied:

record Point(int x, int y) {} static void printSum(Object obj) { if (obj instanceof Point(int x, int y)) { System.out.println(x + y); } }

This inspection depends on the Java feature 'Pattern guards and record patterns' which is available since Java 21.
