Examples of java.io.File.compareTo()

java.io.File.compareTo()
Answers the relative sort ordering of paths for the receiver and given argument. The ordering is platform dependent. @param another a File to compare the receiver to @return an int determined by comparing the two paths. The meaning isdescribed in the Comparable interface. @see Comparable
