BufferedOutputStream
Write byte to file with BufferedOutputStream
With this example we are going to demonstrate how to write a byte to a file with BufferedOutputStream. This class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written. In short, to write a byte to a file with BufferedOutputStream you should:
- Create a FileOutputStream to write to the file with the specified name.
- Create a BufferedOutputStream for the FileOutputStream.
- Use
write(byte b)
API method. It writes the specified byte to this buffered output stream.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core; import java.io.BufferedOutputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; public class WriteByteToFileWithBufferedOutputStream { public static void main(String[] args) { String filename = "output.txt"; BufferedOutputStream bos = null; FileOutputStream fos = null; try { // create FileOutputStream from filename fos = new FileOutputStream(filename); // create BufferedOutputStream for FileOutputStream bos = new BufferedOutputStream(fos); byte b = 23; bos.write(b); } catch (FileNotFoundException fnfe) { System.out.println("File not found" + fnfe); } catch (IOException ioe) { System.out.println("Error while writing to file" + ioe); } finally { try { if (bos != null) { bos.flush(); bos.close(); } } catch (Exception e) { System.out.println("Error while closing streams" + e); } } } }
This was an example of how to write a byte to a file with BufferedOutputStream in Java.
