刚刚假期归来，由于前一段时间加班了一个月，所以假期就实实在在的放松了一下，小工这个假期都快玩疯了，导致上班的时候感觉好累，你们有没有这种感觉？？？
精力有限，分享无限，作为码农的我们，利用有限的精力去积累工作以外的技术点，这样才能迅速的成长。最近一直在看各种各样的博客，有身边朋友的，有各个平台的，一直在寻找着出项目之外的技术点，积累分享，我们不是一个人在行走在简书的道路上，大家一起分享，一起走向技术大牛（扯的有点远了）。

现在贴一下工作当中用到的非常实用的工具类，有了它们让你的代码看起来更加的简洁美观，让你感觉不是在在码砖，而是在进行艺术创造。。。

其他的电话号码，手机号码，字符串等用法和这个类似
/**
* 字符串转换成日期(字符串的格式为yyyy-MM-dd)
*
* @param str//日期字符串
* @return date
*/
public static Date StrToDate(String str) {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Date date = null;
try {
date = format.parse(str);
} catch (ParseException e) {
e.printStackTrace();
}
return date;
}
目前就整理了这些，后面遇到了再继续补充，如果大家有好的工具类，希望帮助补充。。。
