socket地址的通配符地址、环回地址、localhost

今天在写ServerSocket的时候，遇到了socket地址的通配符地址、环回地址、localhost。

package com.thb;

import java.io.IOException;
import java.net.InetAddress;
import java.net.ServerSocket;

public class ServerSocketMain {

	public static void main(String[] args) {
		ServerSocket server = null;
		try {
			server = new ServerSocket(22335);
			InetAddress address = server.getInetAddress();
			System.out.println("ServerSocket绑定的地址："+ address);
			System.out.println("是否通配符地址：" + address.isAnyLocalAddress());			
			System.out.println("是否环回地址：" + address.isLoopbackAddress());
			System.out.println();
			System.out.println("环回地址：" + InetAddress.getLoopbackAddress());
			System.out.println("localhost：" + InetAddress.getLocalHost());			

		} catch (IOException e) {			
			
		} finally {
			try {
				server.close();
			} catch (IOException e) {				
				
			}
		}

	}

}

执行输出：
