Santosh,

I notice that you have well over a hundred posts, so you should know by now that we are NotACodeMill.

All the information you need to answer your first two questions is contained in the Java Collections Framework docs or tutorials. For the third, since I have no idea what you mean by a "wildcard search algorithm", I suggest you start by reading up on regular expressions.

If and when you have tried something or have a specific question, we'll be happy to help.

Winston
