What are best practices for working with TreeMap?

Understanding TreeMap in Java is essential for efficient data management. This guide covers best practices for working with TreeMap, including its usage scenarios, performance considerations, and sorting mechanics.

// Importing necessary classes
import java.util.TreeMap;

public class TreeMapExample {
    public static void main(String[] args) {
        // Creating a TreeMap
        TreeMap map = new TreeMap<>();

        // Adding key-value pairs
        map.put("Apple", 2);
        map.put("Banana", 5);
        map.put("Orange", 3);

        // Displaying the TreeMap
        System.out.println("TreeMap: " + map);

        // Retrieving a value associated with a key
        int count = map.get("Banana");
        System.out.println("Banana count: " + count);

        // Remove a key-value pair
        map.remove("Apple");
        System.out.println("After removing Apple: " + map);

        // Iterate through the TreeMap
        for (String key : map.keySet()) {
            System.out.println(key + ": " + map.get(key));
        }
    }
}
