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.putInt(123);// www. ja  v a  2 s  .  c o  m

    System.out.println(Arrays.toString(bbuf.array()));
}

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.putLong(2, 123);//from  www  .j a va2  s . c o m

    System.out.println(Arrays.toString(bbuf.array()));
}

From source file:Main.java

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