获取ip地址

很实用的小代码，获取IP地址

 

package wingsoft.custom.tools;

import java.net.*;

public class NetInfo { public static void main(String[] args) {
new NetInfo().say();
}
public void say() {
try { InetAddress i = InetAddress.getLocalHost();
System.out.println(i); //计算机名称和IP
System.out.println(i.getHostName()); //名称
System.out.println(i.getHostAddress()); //只获得IP
}
catch(Exception e){e.printStackTrace();}
}
}
