Parse out time portion from ping results in Java

Question

I managed to modify a program to ping peer computer and gets the ping counts. How can I parse out the time = ?ms from the ping count results, in real-time?

Answer 1

You could use indexOf:

pingResult = pingResult.substring(pingResult.indexOf("time="));

Then remove the TTL:

pingResult = pingResult.substring(0, pingResult.indexOf("TTL"));

Therefore, the final code:

Runtime r = Runtime.getRuntime();
Process p = r.exec(pingCmd);

BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
    System.out.println(inputLine);
    pingResult += inputLine;
}
in.close();
pingResult = pingResult.substring(pingResult.indexOf("time=")).substring(0, pingResult.indexOf("TTL"));
