Java data class / record

PointDist.java

public class PointDist {
  public static void main(String[] args) {
    var point = new Point(3, 4);
    System.out.println(String.format("x: %d - y: %d - distance: %f", point.x(), point.y(), point.dist()));
  }

  static record Point(int x, int y) {
    double dist() {
      return Math.sqrt(x * x + y * y);
    }
  }
}

Aaaand it works:

~/Code/java-amber/amber $ build/*/jdk/bin/javac PointDist.java && build/*/jdk/bin/java PointDist
x: 3 - y: 4 - distance: 5.000000
