示例1: listFiles
/**
* Lists the files of the given directory and returns them as an array which
* is never null. This simplifies processing file listings from for each
* loops since {@link File#listFiles} can return null. This method simply
* wraps it and makes sure it returns an empty array instead if necessary.
*
* @param dir the directory to list
* @return the children, or empty if it has no children, is not a directory,
* etc.
