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.putShort(2, (short) 123);
    System.out.println(Arrays.toString(bbuf.array()));

    System.out.println(bbuf.arrayOffset());
}
