What is the purpose of Java OutputStreamWriter?

Java OutputStreamWriter is a class for character streams that is used to write characters into an output stream. It utilizes a specified character encoding when converting characters to bytes.

The main purpose of the OutputStreamWriter class is to convert character streams into byte streams. It provides methods to write characters into an output stream, converting them to byte streams according to a specified character encoding, and then writing them to a target device (such as a file or a network connection).

The functionality can be achieved using OutputStreamWriter.

1. Convert character stream to byte stream: OutputStreamWriter can convert character stream to byte stream, making it convenient to use character operations when working with byte streams.
2. You can specify the character encoding using OutputStreamWriter, which converts characters to byte streams according to the specified encoding to ensure proper handling of character encoding in different environments.
3. OutputStreamWriter provides various methods for writing characters to an output stream, allowing users to write characters to a destination device such as a file or network connection.

In general, the main purpose of OutputStreamWriter is to convert characters to bytes and write them to an output stream, serving as a bridge between character streams and byte streams.
