iam new to java programming and my final year project is based on a Rogue Access point detection tool, and i need to how can i obtain SSID from a java code of the exisiting wifi networks?
for eg: say iam in my laptop i need the program to show how many SSIDs are there broadcasting the SSIDS and the names! (through the built in wifi adapter in the laptop).
Thank you.
Java is a High-Level, Platform-Independent programming language. Network settings, and how you control them will depend on your Operating System, and to my knowledge there is no simple way or an API to expose this,but i tried write a code maybe is helpful for you.
