Java规范

1.修改

在 Windows->Preferences->Java Code Style的Formatter 和 Cleanup 中导入/tools/configures/eclipse/cleanup-profile.xml 和formatter.xml。

在 Windows->Pr4eference->Java->Editor->SaveAction, 选择Format Source Code，Formate All Codes，与Organize Imports

修改Windows->Preferences->XML->XML Files->Editor  ,增加到120字符

2.Formatter的修改记录

在Eclipse built-in 的基础上做出如下修改

• 每行增至120字符 (Line wrapping)
• 取消三个 Comment Format (Comments) --因为Eclipse的Formatter不能自由换行，老把注释搞成一行的缘故

3.Cleanup的修改记录

Change indirect accesses to static members to direct accesses (accesses through subtypes)
Remove unused imports
Add missing '@Override' annotations
