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

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

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.hasArray());
}

From source file:Main.java

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

From source file:Main.java

    bbuf.flip();//from   w  w  w .j a v  a2  s  .  c  om
}

From source file:Main.java

    while ((c = bb.getChar()) != 0)
        System.out.print(c + " ");
    System.out.println();

}

From source file:Main.java
