【Java】获取网卡连接名（用于修改IP地址）

String os = System.getProperty( "os.name" );
  if ( os != null && os.startsWith( "Windows" ) ) {
    try {
       String  command = "cmd.exe /c netsh interface show interface|more +3";
       Process p = Runtime.getRuntime().exec(command);
       BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream(),"GBK"));
       String line;
       while ((line = br.readLine()) != null) {
          if (!line.contains("VMware") && !line.contains("WLAN") && line.length() > 0) {
              int i = line.lastIndexOf("  ");
              String name = line.substring(i).trim();
              //输出网络连接名
              System.out.println(name);
              break;
             }
          }
     } catch (IOException e) {
          e.printStackTrace();
     }
}
