public static final void writeLong(ByteBuffer buffer, long l) {
buffer.put((byte) (l & 0xff));
buffer.put((byte) (l >>> 8));
buffer.put((byte) (l >>> 16));
buffer.put((byte) (l >>> 24));
buffer.put((byte) (l >>> 32));
buffer.put((byte) (l >>> 40));
buffer.put((byte) (l >>> 48));
buffer.put((byte) (l >>> 56));
}
举这个方法的列子,为什么使用这些移位操作,比较疑惑。为什么是8 16 24 32 40 48 56,谢谢。
