Usage

From source file:Main.java

public static void main(String[] args) throws FileNotFoundException, UnsupportedEncodingException {

    Formatter formatter = new Formatter(new FileOutputStream("generated/format.txt"), "ASCII");

    // format a new string
    String name = "from java2s.com";
    formatter.format("Hello %s !", name);

    // print the formatted string
    System.out.println(formatter);

    // flush the formatter. Here it does nothing.
    formatter.flush();/*from w w w .  j  a  v a2 s . co  m*/
    System.out.println("Formatter Flushed.");
}

From source file:Main.java

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

    // write something in the file
    oout.writeUTF(s);//from w  w w.  j  a v a2 s  . co  m
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

    // read and print from index 0 to 7
    byte[] b = new byte[13];
    ois.readFully(b, 0, 7);
