		// Initialization of a Map
		// using Generics
		Map<Integer, String> hashmap1= new HashMap<Integer, String>();

		// Inserting the Elements
		hashmap1.put(1, "Apple");
		hashmap1.put(2, "Banana");
		hashmap1.put(3, "Mango");


		for (Map.Entry mapElement : hashmap1.entrySet()) {
			int key= (int)mapElement.getKey();

			// Finding the value
			String value= (String)mapElement.getValue();
