When I try to check my HTML code, I receive this error. What should I do? *'Starting HTTP Preview at localhost' has encountered a problem.
Port 8080 required by HTTP Preview at localhost is already in use. The Server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

I don't use and install Tomcat, Because I didn't study about jsp yet.
+My operating system is Windows 10.
