How does TreeSet impact performance or memory usage?

TreeSet is a part of Java's Collections Framework that implements the Set interface using a Red-Black tree. It offers a sorted collection with guaranteed log(n) time cost for the basic operations (add, remove, contains). However, it may have higher memory overhead compared to other Set implementations like HashSet due to the storage of pointers and tree-balancing properties.

// Example of TreeSet usage in Java import java.util.TreeSet; public class TreeSetExample { public static void main(String[] args) { TreeSet treeSet = new TreeSet<>(); // Adding elements treeSet.add(10); treeSet.add(5); treeSet.add(20); // Displaying elements for (Integer number : treeSet) { System.out.println(number); // Output will be in sorted order } // Checking for existence if (treeSet.contains(10)) { System.out.println("10 is in the set"); } // Removing an element treeSet.remove(5); System.out.println("After removing 5: " + treeSet); } }
