See Above link. The class you want is probably HttpUrlConnection.

[DavidRyan]

By the way, I noticed you didn't even bother to google

java access a url

Yeah you really "...serch on internet for this purpos, but unable to find any idea..."

And use a spell checker, even if only to prevent putting off people who could help you.

Google refuses to be connected with Yahoo I guess ;)

[DavidRyan]

Did you have an open connection at the time? Also, your firewall may be blocking those ports.

[Banderson]

There is nothing wrong with this code. Read the first line of the exception:

Exception in thread "main" java.net.ConnectException: Connection timed out: connect

Your connection timed out. That's all.
