获取本机名及IP地址

Java网络编程初始，通过JDK中API的调用实现输出本地主机的主机名及IP地址。

所用API：java.net.InetAddress

Host类，为静态内部类，调用API测试

package com.anson.java;

import java.net.InetAddress;
import java.net.UnknownHostException;

/**
* Java单例模式的使用
* 网络编程，获取本机名和IP地址
* @author anson
*
*/
public class Host {

private static Host host=null;
private InetAddress iNetAddress=null;
private String HonstName=null;
private String HostAddress=null;

/**
* 构造
*/
private Host()
{
Init();
}

/**
* 返回唯一实例
* @return
*/
public static Host Instance()
{
try
{
if(host==null)
{
host=new Host();
}
}
catch(Exception e)
{
e.printStackTrace();
}
return host;
}

/**
* 初始化
*/
private void Init()
{
try {
this.iNetAddress=InetAddress.getLocalHost();
this.HonstName=iNetAddress.getHostName();
this.HostAddress=iNetAddress.getHostAddress();
}
catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

/**
* 外调输出
*/
public void Print()
{
System.out.println("主机名："+this.HonstName);
System.out.println("主机IP："+this.HostAddress);
}
}


Test类，测试Host类的使用
package com.anson.java;

public class Test {

/**
* 测试
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

Host host=Host.Instance();
host.Print();
}

}


运行结果：
