// Java Program to Illustrate TreeMap Class

// Importing required classes
import java.util.*;

// Main class
public class Main {

	// Main driver method
	public static void main(String[] args)
	{

		// Creating an empty TreeMap
		Map<String, Integer> hashmap = new TreeMap<>();

		// Inserting entries in the Map
		// using put() method
		hashmap.put("Banana", 100);
		hashmap.put("Orange", 200);
		hashmap.put("Mango", 300);
		hashmap.put("Apple", 400);
		
		// Iterating over Map using for each loop
		for (Map.Entry<String, Integer> e : hashmap.entrySet())

			// Printing key-value pairs
			System.out.println(e.getKey() + " "+ e.getValue());
	}

import java.util.*;

// Declare the variable using the interface of the object for flexibility.
// Non-primative data types only.
Map<Integer, String> mambo = new TreeMap<Integer, String>();

mambo.put(key, value);
// TreeMap will be sorted by key.
// Work with any comparable object as a key.

mambo.put(1, "Monica");
mambo.put(2, "Erica");
mambo.put(3, "Rita");
