獲取本機名及IP地址

Java網絡編程初始，通過JDK中API的調用實現輸出本地主機的主機名及IP地址。

所用API：java.net.InetAddress

Host類，爲靜態內部類，調用API測試

package com.anson.java;

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

/**
 * Java單例模式的使用
 * 網絡編程，獲取本機名和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;
	
	/**
	 * 構造
	 */
	private Host()
	{
		Init();
	}
	
	/**
	 * 返回唯一實例
	 * @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();
		}
	}
	
	/**
	 * 外調輸出
	 */
	public void Print()
	{
		System.out.println("主機名："+this.HonstName);
		System.out.println("主機IP："+this.HostAddress);
	}
}

Test類，測試Host類的使用

package com.anson.java;

public class Test {

	/**
	 * 測試
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		Host host=Host.Instance();
		host.Print();
	}

}

運行結果：
