Krishna,
Although JavaRanch is a great site, especially for those seeking
SCJP certification, JavaRanch is not a hosting service.
If you have just a couple questions available, you might post them in this forum for people to look at and ponder over. However, if you have a lot of questions available, you might want to post them on your own website. If you don't have a website, you might consider signing up for a free site - there are lots of free website providers out there, including
www.geocities.com, for one.
