Public IP Address (time limit)

[Juan Manuel Alberto de los Santos]

I use this code to get the public IP address, it works perfectly, but sometimes takes too long and blocks everything, is there any way to put a time limit ?

for example, if in 5 seconds the program doesn't retrive the IP address, stop and print "couldn't find ip, try later"

java.net.URL URL = new java.net.URL("http://www.whatismyip.org/");
 
java.net.HttpURLConnection Conn = (HttpURLConnection)URL.openConnection();
 
java.io.InputStream InStream = Conn.getInputStream();
 
java.io.InputStreamReader Isr = new java.io.InputStreamReader(InStream);
 
java.io.BufferedReader Br = new java.io.BufferedReader(Isr);
 
 
System.out.print("Your IP address is " + Br.readline());

thanks !

If you look at the JavaDoc for the getInputStream() method you are using (which actually exists in the URLConnection super class), you will see a "See Also" notation that points to the setReadTimeout(int) and getReadTimeout() methods. These can be used to set read timeouts.


The HttpURLConnection class also has a setConnectTimeout(int) method, which is also inherited from the URLConnection superclass. More info is available in the Javadoc for the method (see link).
