FileReader and BufferedReader
FileReader is used for input of
character data from a disk file.
The input file can be an ordinary ASCII,
one byte per character text file.
Reader stream automatically
translates the characters from
the disk file format
into the internal
The characters in the input file might be from
other alphabets supported by the UTF format,
in which case there will be up to four
bytes per character.
In this case, also, characters from the file
are translated into
As with output, it is good practice to use a buffer to improve efficiency. Use BufferedReader for this.
BufferedReader stdin = new BufferedReader(new InputStreamReader( System.in ));
These lines create a
but connect it to an input stream from the
keyboard, not to a file.
(Memory test:) What method reads a line of characters from a BufferedReader?
