You can use system command like below(if you on nix
systems, if your os is windows use ipconfig
in a similar way):您可以使用如下系统命令(如果您在

Runtime r = Runtime.getRuntime();
Process p = r.exec("ifconfig -u |grep ether");
p.waitFor();
BufferedReader b = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line = b.readLine()) != null) {
System.out.println(line);
}
b.close();
On my system it gives:在我的系统上它给出:
