Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("C:/WriteByte.txt");
    DataOutputStream dos = new DataOutputStream(fos);
    dos.writeBytes("this is a test");

    dos.flush();//from   w ww .  ja va2  s  .  com
    dos.close();
}

From source file:Main.java

public static void main(String[] args) throws Exception {

    int bytesWritten = dos.size();
    System.out.println("Total " + bytesWritten + " bytes are written to stream.");
    dos.close();//from w  w w  .  j a v  a  2 s  . c  o m
}

From source file:Main.java
