Comment on Tutorial : Simple Port Scanner application using Java By Syed M Hussain
Small modification.
System.out.println("Port not in use: " + i ); should be INSIDE the catch block. Otherwise, the output is like:
Port not in use: 79
Port in use: 80
Port not in use: 80
Port not in use: 81
Even if a Port is in use, it will print that its not in use.
Modified output
Port not in use: 79
Port in use: 80
Port not in use: 81
Port not in use: 82
