eclipse tipse....to be continued forever.

1.Access restriction: ....is not accessible due to restriction on required library C:/Java/jre1.6.0_07/lib/rt.jar
解决办法:Eclipse默认把这些受访问限制的API设成了ERROR。把Windows-Preferences-Java-Complicer-Errors/Warnings里面的Deprecated and restricted API中的Forbidden references(access rules)选为Warning就可以编译通过。

2.eclipse代码对齐快捷键:ctr+shift+f
