3. Java Streams

4. Streams Java reads and writes data via streams
A stream is a sequence of data (bytes, characters, etc…
We read data from input streams
We write data to output streams

5. Byte Streams
The FileInputStream and FileOutputStreams read and write a sequence of bytes
The read() method reads a byte
The write() method writes a byte
The close() method closes the file

6. Byte Streams (Example)

7. Character Streams
Character streams work the same way as byte streams but operate on 16 bit Unicode characters
The FileReader and FileWriter read and write a sequence of bytes
The read() method reads a character
The write() method writes a character

8. Web Example The InputStream class is the base class for all readers
But we want to read characters which is done via the InputStreamReader
So we wrap the classes
