Usage

From source file:Main.java

/**
 * Read the contents of a file into a single Java String.
 * /* w w  w.  j a  va  2  s .co  m*/
 * @param filename
 *            The file to be read in
 * @return a String containing the contents of filename
 * @throws FileNotFoundException
 *             and IOException on a read error. These are propegated
 *             rather than simply trapped here bcause if reading in files
 *             is somewhat critical to the app and if something goes
 *             wrong, the app needs to take remedial action, probably with
 *             user feedback.
