Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("C:/WriteBoolean.txt");
    DataOutputStream dos = new DataOutputStream(fos);

    boolean b = false;
    dos.writeBoolean(b);
    dos.close();//from   w  w  w  .  j ava 2  s. co  m
}

From source file:MainClass.java

public static void main(String args[]) {
    try {/*from   w w w  . j a v  a 2 s  . c  o m*/

        DataOutputStream dos = new DataOutputStream(fos);

        dos.writeBoolean(false);
        dos.writeByte(Byte.MAX_VALUE);
