Java BufferedOutputStream Class Example

Java BufferedOutputStream class is used for buffering an output stream. It internally uses a buffer to store data. It adds more efficiency than to write data directly into a stream. So, it makes the performance fast.

BufferedOutputStream Class Example

This program uses text content as input and writes to file named "sample.txt".
String content = "This is the text content";
Note: This program uses try-with-resources. It requires JDK 7 or later.
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

        try (OutputStream out = new FileOutputStream(file);
           BufferedOutputStream bout = new BufferedOutputStream(out);) {

         // if file doesn't exists, then create it
          if (!file.exists()) {
              file.createNewFile();
          }
         // get the content in bytes
         bout.write(content.getBytes());
         } catch (IOException e) {
             e.printStackTrace();
         }
    }
}
