Java WriterOutputStream-class And Method Code Example


Here is an example of how to use the WriterOutputStream class from the org.apache.commons.io package in Java:

import java.io.FileWriter;
import java.io.IOException;

import org.apache.commons.io.output.WriterOutputStream;

public class Example {
    public static void main(String[] args) throws IOException {
        FileWriter fileWriter = new FileWriter("example.txt");
        WriterOutputStream writerOutputStream = new WriterOutputStream(fileWriter);
        writerOutputStream.write("Hello, World!".getBytes());
        writerOutputStream.flush();
        writerOutputStream.close();
    }
}

This example creates a FileWriter to write to a file named "example.txt", and then wraps it in a WriterOutputStream. The write method is called on the writerOutputStream object to write the bytes of the string "Hello, World!" to the file. The flush method is called to flush any remaining bytes to the file, and the close method is called to close the stream.

You can also use your own implementation of the Writer by extending the WriterOutputStream class and passing it to the super class constructor, you can use the write method and other methods to execute your own logic, for example, you can use it to convert the bytes to chars and write to a file, or for any other purpose.

Note that, the WriterOutputStream is not intended to be used as a general-purpose class, it is intended to be used only in situations where you need to write a stream to a file and also convert the bytes to chars.
