JAVA分別實現Windows平台和Linux平台下的ip獲取

一般我們很容易獲取Windows系統下的ip信息，比如：

1. package com.han;
2. import java.net.InetAddress;
3. import java.net.UnknownHostException;
5. /**

10. public class InetAddressObtainment_Windows {
11. String hostname;
12. String hostaddress;
13. void initialize(){
14. try {
15. InetAddress ia=InetAddress.getLocalHost(); //獲得本機網絡地址對象
16. hostname=ia.getHostName(); //獲得對應主機名
17. hostaddress=ia.getHostAddress(); //獲得對應主機地址
18. } catch (UnknownHostException e) {
19. // TODO Auto-generated catch block
20. e.printStackTrace();
21. }
22. }
23. public static void main(String[] args){
24. InetAddressObtainment_Windows o1=new InetAddressObtainment_Windows();
25. System.out.println(o1.hostname);
26. System.out.println(o1.hostaddress);
27. o1.initialize();
28. System.out.println(o1.hostname);
29. System.out.println(o1.hostaddress);
30. }
