Java I/O Best Practices

I/O represents Input and Output streams. We use streams to read from or write to devices such as file or network or console. java.io package provides I/O classes to manipulate streams. This package supports two types of streams - binary streams which handle binary data and character streams which handle character data. InputStream and OutputStream are high level interfaces for manipulating binary streams. Reader and Writer are high level interfaces for manipulating character streams.

1. Reading and writing data using default behavior of some streams that is byte by byte  read/write causes slow performance.
2. Buffered input streams and buffered output streams increase performance.
3. Custom buffering increases performance significantly.
