OutputStreamWriter is a class in Java that converts characters into bytes by writing them to an OutputStream. It is a bridge between character streams and byte streams, allowing character data to be written to an OutputStream.
The OutputStreamWriter class provides a way to write characters to an OutputStream in a specified character encoding. It takes a character output stream and a character encoding as input parameters and converts the characters to bytes in the specified encoding before writing them to the output stream.
Some of the commonly used methods of the OutputStreamWriter class are:
- write(char[] cbuf, int off, int len): Writes a portion of an array of characters to the output stream.
- write(int c): Writes a single character to the output stream.
- flush(): Flushes the output stream and writes any buffered output to the underlying stream.
- close(): Closes the output stream and releases any system resources associated with it.
OutputStreamWriter is useful when we need to write character data to an OutputStream, for example, when writing to a file or sending data over a network. It provides a convenient way to convert characters to bytes in a specific encoding and write them to the output stream.
