I’m trying to make java program that checks ip addresses and it’s ports and return whether it is listening or not. Since it is web based programing that I’m doing, I want the program to be really light and efficient. Thanks in advance

You can try to use
SocketAPI from Java for this. If no one is listening at an IP:PORT, you get a “Connection refused” exception thrown. How you want to continue further check if the connection gets accepted is something you would/should know about.
