fastutil extends the Java Collections Framework by providing type-specific maps, sets, lists, and queues with a small memory footprint and fast operations; it provides also big (64-bit) arrays, sets, and lists, sorting algorithms, fast, practical I/O classes for binary and text files, and facilities for memory mapping large files. This jar (fastutil-core.jar) contains data structures based on integers, longs, doubles, and objects, only; fastutil.jar contains all classes. If you have both jars in your dependencies, this jar should be excluded.

The newest version!

/** Provides static methods to perform easily textual I/O.
 *
 * This class fills a gap in the Java API: a natural operation on sequences
 * of primitive elements is to load or store them in textual form. This format
 * makes files humanly readable.
 *
 * 
For each primitive type, this class provides methods that read elements
 * from a {@link BufferedReader} or from a filename (which will be opened
 * using a buffer of {@link #BUFFER_SIZE} bytes) into an array. Analogously,
 * there are methods that store the content of an array (fragment) or the
 * elements returned by an iterator to a {@link PrintStream} or to a given
 * filename.
 *
 * 
Finally, there are useful wrapper methods that {@linkplain #asIntIterator(CharSequence)
 * exhibit a file as a type-specific iterator}.
 *
 * 
Note that, contrarily to the binary case, there is no way to
 * {@linkplain BinIO#loadInts(CharSequence) load from a file without providing an array}. You can
 * easily work around the problem as follows:
 * 
 * array = IntIterators.unwrap(TextIO.asIntIterator("foo"));
 * 
 *
 * @since 4.4
