java获取路由ip_如何在Java中确定路由器/网关的IP？

不幸的是,Java并不像其他语言一样愉快.这是我做的：

import java.io.*;

import java.util.*;

public class ExecTest {

public static void main(String[] args) throws IOException {

Process result = Runtime.getRuntime().exec(&＃8220;traceroute -m 1 www.amazon.com&＃8221;);

BufferedReader output = new BufferedReader(new InputStreamReader(result.getInputStream()));

String thisLine = output.readLine();

StringTokenizer st = new StringTokenizer(thisLine);

st.nextToken();

String gateway = st.nextToken();

System.out.printf(&＃8220;The gateway is %s\n&＃8221;, gateway);

}

}

这假设网关是第二个令牌,而不是第三个令牌.如果是,你需要添加一个额外的st.nextToken();推动分类器一个点.
