Java InetAddress.getByAddress()的使用

import java.net.*;
 
public class NetDemo {
 
    public static void main(String[] args) throws Exception{
 
        String str = "172.20.223.120";
        String[] ipStr = str.split("\\.");
        byte[] ipBuf = new byte[4];
        for(int i = 0; i < 4; i++){
            ipBuf[i] = (byte)(Integer.parseInt(ipStr[i])&0xff);
        }
 
        InetAddress ia = InetAddress.getByAddress("hao.wen",ipBuf);
        System.out.println(ia);
    }
}
