Question

java里面有个函数没看懂~Enumeration<NetworkInterface>什么的。麻烦有人可以帮我解释一下里面的代码~

public String getLocalIpAddress()
{
try {
for(Enumeration<NetworkInterface>en=NetworkInterface.getNetworkInterfaces();en.hasMoreElements();)
{
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr=intf.getInetAddresses();enumIpAddr.hasMoreElements();)
{
InetAddress inetAddress = enumIpAddr.nextElement();
recvMessageServer += "请连接IP："+inetAddress.getHostAddress()+":"
+ serverSocket.getLocalPort()+ "\n";
}
}
}
麻烦帮我注解一下上面的代码功能。~求大神~
