Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ByteBuffer bbuf = ByteBuffer.allocate(10);
    int capacity = bbuf.capacity(); // 10
    System.out.println(capacity);
    bbuf.put((byte) 0xFF);
    bbuf.position(5);// w  w w.  j ava  2  s  .  c  om
    bbuf.put((byte) 0xEE);
    System.out.println(Arrays.toString(bbuf.array()));
}

From source file:Main.java

public static void main(String[] args) {

    ArrayList<Integer> arrlist = new ArrayList<Integer>(5);

    arrlist.add(20);/*ww w. jav  a  2 s . c o m*/
    arrlist.add(40);
    arrlist.add(10);
    arrlist.add(15);
    arrlist.add(25);

    Object[] ob = arrlist.toArray();

    System.out.println(Arrays.toString(ob));

}

From source file:Main.java

public static void main(String args[]) {

}

From source file:Main.java

    stringReader.read(charArray);//www  .  j av a2  s. com
    System.out.println(Arrays.toString(charArray));

    stringReader.close();
}

From source file:Main.java
