Creates a new buffered output stream to write data to the specified underlying output stream.

Usage

From source file:TestCipher.java

public static void main(String args[]) throws Exception {
    Set set = new HashSet();
    Random random = new Random();
    for (int i = 0; i < 10; i++) {
        Point point = new Point(random.nextInt(1000), random.nextInt(2000));
        set.add(point);//  w w  w  .  j  a  v  a  2 s.  com
    }
    int last = random.nextInt(5000);

    // Create Key
    byte key[] = password.getBytes();
    DESKeySpec desKeySpec = new DESKeySpec(key);
    SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
    SecretKey secretKey = keyFactory.generateSecret(desKeySpec);

    // Create Cipher
    Cipher desCipher = Cipher.getInstance("DES/ECB/PKCS5Padding");
    desCipher.init(Cipher.ENCRYPT_MODE, secretKey);

    // Create stream
    FileOutputStream fos = new FileOutputStream("out.des");
    BufferedOutputStream bos = new BufferedOutputStream(fos);
    CipherOutputStream cos = new CipherOutputStream(bos, desCipher);
    ObjectOutputStream oos = new ObjectOutputStream(cos);

    // Write objects
    oos.writeObject(set);
    oos.writeInt(last);
    oos.flush();
    oos.close();

    // Change cipher mode
    desCipher.init(Cipher.DECRYPT_MODE, secretKey);

    // Create stream
    FileInputStream fis = new FileInputStream("out.des");
    BufferedInputStream bis = new BufferedInputStream(fis);
    CipherInputStream cis = new CipherInputStream(bis, desCipher);
    ObjectInputStream ois = new ObjectInputStream(cis);

    // Read objects
    Set set2 = (Set) ois.readObject();
    int last2 = ois.readInt();
    ois.close();

    // Compare original with what was read back
    int count = 0;
    if (set.equals(set2)) {
        System.out.println("Set1: " + set);
        System.out.println("Set2: " + set2);
        System.out.println("Sets are okay.");
        count++;
    }
    if (last == last2) {
        System.out.println("int1: " + last);
        System.out.println("int2: " + last2);
