i have two things one is vector (vec) and a map ( map ) and the code
will be
for ( int i = 0;i<vec.size() ;i++ )
{
      Class obj = ( Class )vec.get( i );
      for ( Iterator it = map.keySet().iterator();it.hasNext();)
      {
                  key = (String)it.next();
                  Class2 obj2 = ( Class2 )map.get( key );
                  if (!info.contains(obj2))
                  {
                                v1.add(obj);
                   }
                   else
                    v1.remove(obj);
               }
      }
}

here what would be the result.  becoz i get the answers as a repeated
one.
