在java中Ping值

Question

我知道这个问题已经以不同的方式处理,但我已经检查了stackoverflow并且我没有找到我正在寻找的答案.

为简单起见:有没有办法在Windows下为Windows服务器获取Time ping值？

我知道如何检查某些服务器是否可访问,但我希望有精确的值,就像我们可以在终端上阅读一样.

感谢您的帮助和理解.

你可以这样做:

//The command to execute
String pingCmd = "ping " + ip + " -t";

//get the runtime to execute the command
Runtime runtime = Runtime.getRuntime();
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 = 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);
        }
    }
}

写得很匆忙.
