There are four types of streams: InputStream, OutputStream, Reader, and Writer. |
- Reader. A stream to read characters.
- Writer. A stream to write characters.
- InputStream. A stream to read binary data.
- OutputStream. A stream to write binary data.

For better performance, use the buffered I/O classes:
BufferedInputStream,
BufferedOutputStream,
BufferedReader, and
BufferedWriter. |
Reading from and writing to a stream dictate that you do so sequentially.
The java.io.RandomAccessFile is for non-sequential operations. |
For object serialization and deserialization, you can use the ObjectInputStream and ObjectOutputStream classes. |
