How to clear the port in use in windows?

Question

Windows

I put port 8080, I need to clear it, but I don't know how

Answer 1

The wording of the question begs for an appropriate answer...
But in essence, you can find out which program occupies the port
netstat -aon | findstr 8080
then
tasklist /fi "PID eq 12345"
- replace 12345 with the number from the output of the first command

Answer 2

What does "clear" mean? If you need to release, then just beat the process that took it.

Answer 3

Port is a number.
Used when transmitting packets over the network. A number is added to the package name so that the recipient knows to whom to send the package.
Please explain how the number can "lay"? What do you mean by this?
