JAVA學習筆記-----------InetAddress 的有關IP地址的使用案例（雜亂）

package com.package_Server;
import java.io.*;
import java.net.*;
import java.awt.*;
public class Server_test 
{
  
public static void main(String[] args)
{
Server_test st=new Server_test();


}

public Server_test()
  {


try {
byte[] bs=new byte[]{(byte)192,(byte)168,120,54};
System.out.println(InetAddress.getByAddress(bs));
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}



/*try {
            InetAddress addr = InetAddress.getByName("127.0.0.1");
            System.out.println(addr.toString());
            System.out.println(InetAddress.getByName(addr.getHostName()) == addr);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }這個可以正常執行*/
        
       /* try {
InetAddress addr = InetAddress.getByName("192.168.120.54");
String IP=addr.toString();
System.out.println(IP);
System.out.println(addr.toString());

// TODO Auto-generated catch block
e.printStackTrace();
}
*/



        
/*try {
String ip="192.168.120.54";
InetAddress addr=InetAddress.getByName(ip);
String IP=addr.toString();
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println(addr);
*/
/*try {
