Examples of java.io.FileOutputStream

java.io.FileOutputStream
FileOutputStream is a class whose underlying stream is represented by a file in the operating system. The bytes that are written to this stream are passed directly to the underlying operating system equivalent function. Since overhead may be high in writing to the OS, FileOutputStreams are usually wrapped with a BufferedOutputStream to reduce the number of times the OS is called.
BufferedOutputStream buf = new BufferedOutputStream(new FileOutputStream("aFile.txt")); @see FileInputStream

      tempFile.deleteOnExit();


      ObjectOutputStream oos = 
  new ObjectOutputStream(
  new BufferedOutputStream(
  new FileOutputStream(tempFile)));
    
      oos.writeObject(m_Instances);
      oos.flush();
      oos.close();
