Usage

From source file:MainClass.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.wrap(new byte[12]);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.array()));
    bb.rewind();//from ww  w .j  a  v a2s. c  o m
    bb.order(ByteOrder.BIG_ENDIAN);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.array()));
    bb.rewind();
    bb.order(ByteOrder.LITTLE_ENDIAN);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.array()));
}

From source file:Endians.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.wrap(new byte[12]);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.array()));
    bb.rewind();/*from w  w w.  j ava  2s  .c o  m*/
    bb.order(ByteOrder.BIG_ENDIAN);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.array()));
    bb.rewind();
    bb.order(ByteOrder.LITTLE_ENDIAN);
    bb.asCharBuffer().put("abcdef");
    System.out.println(toString(bb.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.putShort(2, (short) 123);

    ByteOrder byteOrder = bbuf.order();

    System.out.println(byteOrder);
}

From source file:MainClass.java

public static void main(String[] argv) throws Exception {
    ByteBuffer bb = ByteBuffer.allocate(20);
