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

Google refuses to be connected with Yahoo I guess 
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

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

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.

Exception in thread "main" java.net.ConnectException: Connection timed out: connect
Your connection timed out. That's all.
