Streams
- All modern I/O is stream-based
- A stream is a connection to a source of data or to a destination for data (sometimes both)
- An input stream may be associated with the keyboard
- An input stream or an output stream may be associated with a file
- Different streams have different characteristics:
- A file has a definite length, and therefore an end
- Keyboard input has no specific end
How to do I/O
import java.io.*;- Open the stream
- Use the stream (read, write, or both)
- Close the stream
