Example to show Enumeration exception in java

     

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[5]. 

To remove the exception from the program defined below you have to give the proper index in the method list.remove(5).

EnumerationException.java


import java.util.*;

public class EnumerationException {

  public static void main(String[] args) {
  try {
  ArrayList<String> list = new ArrayList<String>();
  list.add("girish");
  list.add("roseindia");
  list.remove(5);
  Iterator<String> it = list.iterator();
  while (it.hasNext()) {
  String s = it.toString();
  System.out.println(s);
  }
  catch (Exception ex) {
  System.out.println("cannot remove this index elemnt");
  }
  }
}

 

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).
