public class CheckValueOfHashTableExample {

	public static void main(String[] args) {

		// Create a HashTable object
		Hashtable hTable = new Hashtable();

		// Put Key-value
		hTable.put("1", "January");
		hTable.put("2", "February");
		hTable.put("3", "March");
		
		//To check that the HashTable contains the specified value, use the containsValue() method
		boolean b1 = hTable.containsValue("January");
		boolean b2 = hTable.containsValue("April");

		System.out.println("Value January:" + b1 + "nValue April:" + b2);
