ByteConversionUtil ByteBuffer java编译错误

Question

完成了我的代码，但经过多次调试，我仍然无法成功编译它。问题就在这里，但我似乎找不到正确的方法来纠正它。

private static class ByteConversionUtil {
    private static ByteBuffer longBuffer = ByteBuffer.allocate(Long.BYTES);
    private static ByteBuffer intBuffer = ByteBuffer
            .allocate(Integer.BYTES);
    private static byte[] longToByteArray(long value) {
        longBuffer.putLong(0, value);
        return longBuffer.array();
    }
    private static int byteArrayToInt(byte[] array) {
        intBuffer.put(array, 0, array.length);
        intBuffer.flip();
        return intBuffer.getInt();
    }

Answer 1

据我所知，您可能想更改中的代码

private static ByteBuffer longBuffer = ByteBuffer.allocate(Long.BYTES);
private static ByteBuffer intBuffer = ByteBuffer.allocate(Integer.BYTES);

至

private static ByteBuffer longBuffer = ByteBuffer.allocate(Long.SIZE);
private static ByteBuffer intBuffer = ByteBuffer.allocate(Integer.SIZE);

Long.SIZE为缓冲区分配64个字节
Integer.SIZE为缓冲区分配32个字节。
