Redundant record constructor

Reports redundant constructors declared inside Java records.

Example 1:

record Point(int x, int y) { public Point {} // could be removed } record Point(int x, int y) { public Point(int x, int y) { // could be removed this.x = x; this.y = y; } }

The quick-fix removes the redundant constructors.

Example 2:

// could be converted to compact constructor record Range(int from, int to) { public Range(int from, int to) { if (from > to) throw new IllegalArgumentException(); this.from = from; = to; } }

The quick-fix converts this code into a compact constructor.
