Java - Wifi API

Question

I am trying to find out if there is a Wifi API for Java. Something that can connect to Wifi networks and scan them (to find devices). I can't seem to find something like that. Any suggestions? Thanks!

P.S. I know about the WifiManager for Android, but I am not developing for Android, I am developing with JDK 6.

You can take help of command line tools to get list of available networks using command "netsh wlan show networks mode=Bssid". Try below java method.

public static ArrayList scanWiFi() {
        ArrayList<String> networkList = new ArrayList<>();
        try {
            // Execute command
            String command = "netsh wlan show networks mode=Bssid";
            Process p = Runtime.getRuntime().exec(command);
            try {
                p.waitFor();
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(p.getInputStream())
            );
            String line;
            StringBuilder sb = new StringBuilder();
            String ssidArr[];

            while ((line = reader.readLine()) != null) {
                //System.out.println(line);
                if (line.contains("SSID ") && !line.contains("BSSID ")) {
                    sb.append(line);
                    networkList.add(line.split(":")[1]);
                    //System.out.println("data : " + ssidArr[1]);
                }
            }
            //System.out.println(networkList);            
        } catch (IOException e) {
        }
        return networkList;
    }
