Indeed - welcome, Seema - it's great to have you here with us this week. Maybe (just maybe), you'll love it here so much that you'll just have to stay.
Kripal, please try to keep your posts on topic. Seema's presence here is concerning JDK 1.4, not 1.5. Additionally, there is no SCJP exam yet for JDK 1.5, so any questions regarding 1.5 really belong in the Java in General forums, rather than the SJCP forum.
