[原创] Java 天气预告 - htmlparser2.0 + httpclient4.0

Java控制台版 - 天气预告

    前段时间，没事儿的时候，就写了一个查看天气预告的小程序，就当学习了！现在将源代码贴上供大家交流。
（程序没有经过优化，仅供大家参考）
（有时候没优化的程序可能更适合学习使用哟！哈哈哈！让大家见笑了啊！）
（其它源代码参见附件，附件中有所需的所有jar包）

主方法：

import java.io.File;
import java.util.Map;

import net.sf.json.JSONObject;

import org.apache.commons.io.FileUtils;
