java得到IPAddress 和 MACAddress

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.InetAddress; import java.net.UnknownHostException; public class IPAddress { public static String getIpAddress() { InetAddress address = null; try { address = InetAddress.getLocalHost(); } catch (UnknownHostException e) { e.printStackTrace(); } return address.getHostAddress(); } public static String getMACAddress() { String address = ""; String os = System.getProperty("os.name"); if (os != null && os.startsWith("Windows")) { try { String command = "cmd.exe /c ipconfig /all"; Process p = Runtime.getRuntime().exec(command); BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream())); String line; while ((line = br.readLine()) != null) { if (line.indexOf("Physical Address") > 0) { int index = line.indexOf(":"); index += 2; address = line.substring(index); break; } if (line.indexOf("物理地址") > 0) { int index = line.indexOf(":"); index += 2; address = line.substring(index); break; } } br.close(); return address.trim(); } catch (IOException e) { e.printStackTrace(); } } return address; } public static void main(String[] args) { System.out.println("IPAddress:"+IPAddress.getIpAddress()); System.out.println("MACAddress:"+IPAddress.getMACAddress()); } }
