windows view port occupancy

Execute in the windows command line window:

-
C:\>netstat -aon | findstr "4444"

TCP    127.0.0.1:4444         0.0.0.0:0              LISTENING       2434
-

It can be seen from the above that the port is occupied by the process whose process number is 2434. Continue to execute the following command:

-
C:\>tasklist | findstr "2434"

javaw.exe                     2434 Console                 0     16,064 K
-

In this way, you can easily kill javaw.exe to free up port 4444
