Here, V is the type of value maintained by the container.
Parameters
No parameter is required.
Return Value

Example:
In the example below, the java.util.Dictionary.elements() method returns an enumeration of the values in the given dictionary.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//creating a dictionary
Dictionary<Integer, String> Dict =
new Hashtable<Integer, String>();
//populating dictionary
Dict.put(101, "John");
Dict.put(102, "Marry");
Dict.put(103, "Kim");
Dict.put(104, "Sam");
Dict.put(105, "Jo");
//printing the content of the dictionary
System.out.println("Dict contains: " + Dict);
//creating an Enum of values of the dictionary
Enumeration MyEnum = Dict.elements();
//printing the Enum info
System.out.println("MyEnum is: " + MyEnum);
//printing the content of the Enum
System.out.print("MyEnum contains: ");
while (MyEnum.hasMoreElements()) {
System.out.print(MyEnum.nextElement() + " ");
}
}
}
The output of the above code will be:
Dict contains: {105=Jo, 104=Sam, 103=Kim, 102=Marry, 101=John}
MyEnum is: java.util.Hashtable$Enumerator@2f2c9b19
MyEnum contains: Jo Sam Kim Marry John
