        // Create a properties and add some values
        Properties properties = new Properties();
        properties.put("Pen", 10);
        properties.put("Book", 500);
        properties.put("Clothes", 400);
        properties.put("Mobile", 5000);
  
        // Print Properties details
        System.out.println("Current Properties: "
                           + properties.toString());
  
        // Creating an empty enumeration to store
        Enumeration enu = properties.elements();
  
        System.out.println("The enumeration of values are:");
  
        // Displaying the Enumeration
        while (enu.hasMoreElements()) {
            System.out.println(enu.nextElement());
        }
    }
}

Output:

Current Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
