How many ways are there in Java to handle input/output (IO)?
There are several ways in which Java handles IO:
- Byte Stream: reading and writing data in units of bytes, mainly including InputStream and OutputStream.
- FileInputStream reads byte data from a file.
- FileOutputStream: Writing byte data to a file.
- BufferedInputStream and BufferedOutputStream: Enhancing read and write efficiency through the use of buffers.
- Character Stream: Reading and writing data unit by unit based on characters, primarily consisting of Readers and Writers.
- FileReader: Reading character data from a file.
- FileWriter: writing character data to a file.
- BufferedReader and BufferedWriter: using a buffer to improve reading and writing efficiency.
- Object Stream: It allows for the direct reading and writing of Java objects, primarily through ObjectInputStream and ObjectOutputStream.
- ObjectInputStream: Reads objects from an input stream.
- ObjectOutputStream: Writes objects to an output stream.
- Conversion Stream refers to the use of InputStreamReader and OutputStreamWriter for converting between character streams and byte streams.
- InputStreamReader: Converts a byte stream to a character stream.
- OutputStreamWriter: Convert character stream to byte stream.
- Standard input/output streams are used for interacting with the console, primarily including System.in and System.out.
- System.in is the standard input stream, used for reading data from the console.
- System.out is the standard output stream used for displaying data on the console.
- File Class: used for file operations, primarily including the File class and related classes.
- File: abstract representation of a path name for a file or directory.
- FileReader and FileWriter: used for performing character stream read and write operations on files.
- FileInputStream and FileOutputStream: used for reading and writing byte streams to files.
The above are common ways Java deals with IO. Choose the appropriate method based on your specific needs.
