Java中的Ping值

Question

我知道已经以不同的方式解决了这个问题，但是我检查了stackoverflow，但没有找到想要的答案。

简而言之：是否有办法在 Windows 下将 Time ping值 获取到IP服务器？ __

我知道如何检查某些服务器是否可以访问，但是我想拥有精确的值，就像我们可以在终端上阅读一样。

感谢您 的帮助和理解。

您可以执行以下操作：

//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);
        }
    }
}
