Creates a byte buffer based on a newly allocated byte array.

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 {
    ByteBuffer bbuf = ByteBuffer.allocate(10);
    int capacity = bbuf.capacity(); // 10
    System.out.println(capacity);
    bbuf.put(0, (byte) 2);

    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.putChar('a');

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

From source file:MainClass.java

}

From source file:Main.java

public static void main(String[] args) {

    bb.rewind();
    System.out.println(bb.getDouble());

}

From source file:Main.java

public static void main(String[] args) {
    ByteBuffer bb = ByteBuffer.allocate(2);
    System.out.println("Default  Byte  Order: " + bb.order());
    bb.putShort((short) 300);
    bb.flip();/*from ww w.jav a2 s .  c  om*/
    showByteOrder(bb);

    bb.clear();
    bb.order(ByteOrder.LITTLE_ENDIAN);
    bb.putShort((short) 300);
    bb.flip();
    showByteOrder(bb);
}

From source file:Main.java

    bb.asShortBuffer().put((short) 471142);
    bb.rewind();/*w ww  . j a va  2  s.  c  o  m*/
    System.out.println(bb.getShort());

}
