Vector remove element

[supriya acharya]

Hello

I have vector containing 69 elements. And i am removing some elements from vector.But my code is not able to remove that element.

here is my code

System.out.println("Messages vector size before deletion :"+messages.size());
 boolean ans =  messages.removeElement(deleted[i]);
 System.out.println("Bool :"+ans);
 System.out.println("Messages vector size after deletion :"+messages.size());

deleted array contains indexes that are to be removed.output i am getting is

Messages vector size before deletion :69
Bool :false
Messages vector size after deletion :69

check this:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Vector.html#remove(java.lang.Object)

Returns: true if the Vector contained the specified element.

so if You get false returned Vector simply doesn't contain element You want to remove.

Read the API documentation for Vector, and see what it means when remove returns false.
Have a look at the remove method description. Try as a debugging exercise preceding that with

System.out.printf("The vector %s this message: %s.%n", messages.contains(deleted[i]) ? "does" : "does not", deleted[i]);//test

What format is deleted[i] in? Is it a message?

Actually i have used list itrator to list the elements in the array and problem was first i was doing messages.remove(deleted[i]) so it was searching for object deleted[i] which actually should messages.removeElementAt(deleted[i]) that means it will delete object at index indicated by deleted[i]
