Java I/O streams; what are the differences?

Tags:

java.io has many different I/O streams, (FileInputStream, FileOutputStream, FileReader, FileWriter, BufferedStreams... etc.) and I am confused in determining the differences between them. What are some examples where one stream type is preferred over another, and what are the real differences between them?

How many types of I O streams are there in Java?

There are 3 categories of classes in java.io are as follows: Input Streams. Output Streams. Error Streams.

What is the difference between input and output stream in Java?

InputStream Read data from the source once at a time. 2. OutputStream Write Data to the destination once at a time.

Streams: one byte at a time. Good for binary data.

Readers/Writers: one character at a time. Good for text data.

Anything "Buffered": many bytes/characters at a time. Good almost all the time.
