This class provides a convenient way to read a line from the
underlying reader. If the operation returns an empty string, the
end of the file has been reached and there is nothing more to
read. strings to an array of strings if the expected output is
in one form rather than another. Therefore, the last non-comment
line in the code snippet above is optional. Loading structured
data from a file A good example of structured data is
line-by-line entries in an input file. Each line is a key-value
pair separated by characters. The key values are populated into
the data structure of the public interface.
Each pair is extracted. Read a line from the file, parse it and
populate it into the map before moving on to the next line. The
following code snippet provides an Phone Number List

of classes. This class is available as part of the core library
under the package. The class contains methods that read the file
one line at a time and then parse the line to create key-value
pairs. The object also implements the familiar map object, which
allows access to individual key values by key name.

Load a set of records from a file. In this case, assume a single
file contains a collection of records, where each record is a
collection of variable-length bytes. More information can be
extracted based on each record. However, this is only done after
the record is loaded into application memory. To write records
to a file, use the following method For each record, first write
bytes of data to the file.
