Perhaps you should have read the posting guidelines first.
You should read a tutorial on how to use the java.net package and the try to write your own code and post it and we can then help from there.

That's better. You left out the code tags which I've already added for you. What you should also add is an explanation of what problem it is giving. You simply said that it is not working. Where/when is it not working? Explain the problem more precisely.

  1. destinationurl = new URL("destination");
  2.  
it should be?

Over longer distances I start to see some lagging, the GUI loses some responsiveness, it's...

The easy way to turn off automatic updates for Windows 10/11
by: Hystou | last post by:
Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
