Before Java 21, accessing record components required calling accessor methods: Object obj = new ColoredPoint(new Point(3, 4), "red"); if (obj instanceof ColoredPoint cp) { int x = cp.https://devops-monk.com/tutorials/java17/records/Mon, 04 May 2026 00:00:00 +0000https://devops-monk.com/tutorials/java17/records/Finalized in Java 16 (JEP 395). Available in all Java 16+ releases, including Java 17. Previous previews: Java 14 (JEP 359) and Java 15 (JEP 384). The Problem: Data Classes in Java Writing a simple immutable data class in Java 11 requires significant boilerplate: public final class Point { private final int x; private final int y; public Point(int x, int y) { this.x = x; this.y = y; } public int x() { return x; } public int y() { return y; } @Override public boolean equals(Object o) { if (this == o) return true; if (!
