Java中的Ping值

您可以执行以下 *** 作：

//The command to executeString pingCmd = "ping " + ip + " -t";//get the runtime to execute the commandRuntime runtime = Runtime.getRuntime();Process process = runtime.exec(pingCmd);//Gets the inputstream to read the output of the commandBufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));//reads the outputsString inputLine = in.readLine();while ((inputLine != null)) {    if (inputLine.length() > 0) {       ........    }    inputLine = in.readLine();}

更新： 根据您的需要

public class PingDemo {        public static void main(String[] args) {        String ip = "localhost";        String time = "";        //The command to execute        String pingCmd = "ping " + ip;        //get the runtime to execute the command        Runtime runtime = Runtime.getRuntime();        try { Process process = runtime.exec(pingCmd); //Gets the inputstream to read the output of the command BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream())); //reads the outputs String inputLine = in.readLine(); while ((inputLine != null)) {     if (inputLine.length() > 0 && inputLine.contains("time")) {          time = inputLine.substring(inputLine.indexOf("time"));          break;       }     inputLine = in.readLine(); }     System.out.println("time --> " + time); } catch (Exception ex) { System.out.println(ex);        }    }}
