public static String pingServer() {
PingResult result = new PingResult();
String jsonString = null;
try {
String command ="ping -c 3 192.168.8.185";
Process p = Runtime.getRuntime().exec(command);
int status = p.waitFor();
InputStream input = p.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(input));
StringBuffer buffer = new StringBuffer();
String line ="";
while ((line = in.readLine()) != null) {
buffer.append(line);
buffer.append("
");
}

String bufferStr = buffer.toString();
System.out.println(bufferStr);

} catch (Exception e) {
System.out.println("---------------exception-----------ping");
System.out.println(e.getMessage());
// e.printStackTrace();

}
}

BufferStr始终获取最后一行数据。

传输3个包，3个接收，0％丢包，时间2000ms

细节结果可以得到。
