Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("test.txt", true);
    fos.write("Appended".getBytes());
    fos.close();/*from w  ww.j a  va  2  s  . com*/
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileOutputStream fos = new FileOutputStream("C:/demo.txt", true);
    fos.write("Appended".getBytes());
    fos.close();/*from  w  ww. j a v a 2s.co  m*/
}

From source file:Test.java

public static void main(String[] args) throws Exception {
    Lock myLock = new ReentrantLock();
    Random random = new Random();

    myLock.lock();/*from  ww  w.j  a  v a2s  .  c  om*/
    int number = random.nextInt(5);
    int result = 100 / number;
    System.out.println("A result is " + result);
    FileOutputStream file = new FileOutputStream("file.out");
    file.write(result);
    file.close();
}

From source file:Main.java
