Enumeration is mean of retaining all the series of element at a time. An object implement interface generates a series of all element at single time. This is read only. We cannot change the value of an object or value in the collection.
Understand with Example
Array List<String> list = new Array List<String>()
Create an Array list of type
list.add("girish"):-This is the method of adding an element to the list.
it.has next ( ) - This method return you the next value if the value is set in list.
The System show you an exception if there is no element specified in index.
To remove the exception from the program defined below you have to give the proper index in the method list.remove(5).
Output of the program
|cannot remove this index elemnt|
Note:-To remove this exception you have to give the proper index in the method list.remove(5).
