Java I/O

  • ‌It is used to process the input and produce the output.

  • It uses stream to make operations faster.

  • java io package contains all the classes for IO.


‌Stream

  • ‌Sequence of data

  • Stream is made of byte


‌Java FileOutputStream:

  • ‌output stream used for writing data to a file


Java FileInputStream :

  • It is used to read data in the form of bytes from file. It is used for reading byte-oriented data like audio, video, image and etc.

  • Java BufferedOutputStream:

  • It internally uses buffer to store data.

  • It is more efficient way to write data than FileOutputStream public class BufferedOutputStream extends FilterOutputStream  


Java BufferedInputStream:

  • BufferedInputStream class is used to read information from stream It internally uses buffer mechanism to make the performance fast


Java SequenceInputStream

  • Java SequenceInputStream class is used to read data from multiple streams.

  • It reads data sequentially


Java ByteArrayOutputStream

  • It is used to write common data into multiple files.

  • It holds a copy and forwards it to multiple streams.


Java DataOutputStream

It writes primitive Java data types to the output stream in a machine-independent way.


Java DataInputStream

It reads primitive data from the input stream in a machine-independent way.


What is character encoding?

  • Since every data in computer is represented in bytes and Strings are essentially collection of characters.

  • To convert bytes into character JVM needs to know which combination of bytes represent which character and this is what character encoding tells JVM.

  • There are many languages in the World like English, Tamil, Telugu and etc.

  • This is the reason why we need to give correct character encoding while converting the bytes to String.


Java FileWriter

  • It is used to write character-oriented data to a file.

  • Unlike FileOutputStream class, you don't need to convert string into byte array because it provides method to write string directly.


Java BufferedWriter

  • It is used to provide buffering for Writer instance.

  • It makes the performance fast.
