静态导入

1 让程序更具可读性

files = Iterables.transform(
  Iterables.filter(
      Iterables.filter(getPagesList(),WebPage.class),undeletedPages),
  new PagesToFilesTransformation()))

静态导入后

import static Iterables.*;

transform(
   filter(
      filter(getPagesList(),WebPage.class), undeletedPages),
   new PagesToFilesTransformation()))
