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.
Pleease help :-(

The code is incomplete. You have a reference to "info" that is never
declared or explained anywhere.

What do you want to achieve?

Is your question "What output would this code produce?"? If so, why
don't you simply run it and see?

Sorry Timo,
Its not "info" The corrected 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 (!vec.contains(obj2))
{
v1.add(obj);
}
else
v1.remove(obj);
}
}

}

Sorry, I still don't know what you want to achieve.

You should explain what you want to do, and where your program fails. It
also would help (us _and_ you) to use meaningful variable names.
