Buffered streams can improve performance by reducing the number of I/O operations. Here's an example:
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
public class BufferedStreams
public static void main(String[] args)
try (BufferedInputStream bis = new BufferedInputStream(new FileInputStream("input.txt"));
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream("output.txt")))
int byteValue;
while ((byteValue = bis.read()) != -1)
bos.write(byteValue);
catch (IOException e)
System.err.println("Error using buffered streams: " + e.getMessage());
To write to a file, you can use the following code:
import java.io.FileOutputStream;
import java.io.IOException;
public class WriteToFile
public static void main(String[] args)
try (FileOutputStream fos = new FileOutputStream("example.txt"))
String data = "Hello, World!";
fos.write(data.getBytes());
catch (IOException e)
System.err.println("Error writing to file: " + e.getMessage());
