Java ProxyOutputStream-class And Method Code Example


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

import java.io.FileOutputStream;
import java.io.IOException;

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

public class Example {
    public static void main(String[] args) throws IOException {
        FileOutputStream fileOutputStream = new FileOutputStream("example.txt");
        ProxyOutputStream proxyOutputStream = new ProxyOutputStream(fileOutputStream);
        proxyOutputStream.write("Hello, World!".getBytes());
        proxyOutputStream.flush();
        proxyOutputStream.close();
    }
}

This example creates a FileOutputStream to write to a file named "example.txt", and then wraps it in a ProxyOutputStream. The write method is called on the proxyOutputStream 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 OutputStream by extending the ProxyOutputStream 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 for logging, or for any other purpose.
