An annotation on a constructor that shows how the parameters of that constructor correspond to the constructed object's getter methods. For example:

   public class Point {
       @ConstructorProperties({"x", "y"})
       public Point(int x, int y) {
           this.x = x;
           this.y = y;
       }

       public int getX() {
           return x;
       }

       public int getY() {
           return y;
       }

       private final int x, y;
   }
The annotation shows that the first parameter of the constructor can be retrieved with the {@code getX()} method and the second with the {@code getY()} method. Since parameter names are not in general available at runtime, without the annotation there would be no way to know whether the parameters correspond to {@code getX()} and {@code getY()} or the other way around.
