Using Java's NavigableSet for Efficient Data Navigation

NavigableSet in Java is a rich interface that extends SortedSet, offering advanced navigation capabilities to handle sorted sets. It provides specialized methods like 'lower', 'floor', 'ceiling', and 'higher' for retrieving elements based on their position relative to a specified target. These methods make NavigableSet highly effective for tasks where ordered retrieval is crucial, such as in priority queues or managing sorted data collections. Its implementation in the standard library, typically through TreeSet, makes it a versatile tool for a wide array of Java applications needing efficient sorted data handling.

This code demonstrates the use of NavigableSet in Java. It creates a TreeSet, adds elements, and uses methods like 'lower', 'floor', 'ceiling', and 'higher' to access elements. It concludes by printing the set in descending order.
