因工作项目的需要，从C#转Java也有很长一段时间了，决定记载归纳一下这半年到底学了什么，到了一个什么程度，当然其间可能会有一些关于.NET的对比。
这是这个系列的目录，我准备按照我的归纳学习点来写，或者说回忆来写也行，所以可能不是很连贯，但我相信，如果你耐心一篇篇看下去，相信也会有所收获的，毕竟这全是一手资料。
我的环境是Windows7 32bit 旗舰版, 将会使用以下工具：
JDK7u25 (有一种怪癖，下载安装完之后，重新卸载后复制出JDK和JRE，然后重新设JAVA_HOME/CLASSPATH的.)
Maven3.1.0 (后来因为不能在cmd下面运行android的安装编译，所以改回了Maven3.0.4版了，详细原因我在这里解释了)
以上工具下载完之后，记得加上系统的环境变量，特别值得一提的是mysql的my.ini中使用如下配置，然后用mysqld --console测试mysql服务是否启动成功。
[mysqld] # These are commonly set, remove the # and set as required. basedir = E:/Java/mysql-5.6.13-win32 datadir = E:/Java/mysql-5.6.13-win32/data port = 3306 # server_id = ..... character-set-server = utf8 collation-server = utf8_general_ci
同样值得一提的是这个Kepler下载回来之后，自动会有M2E插件，我原来还想去
手动安装，发现不需要，看来Maven是趋势了。
另外，为了让Eclipse编写出来的代码的美观，我们可以设定Code Templates和Formatter.
