Java:错误 "Incompatible datatypes"

Question

private byte[] decode_text(byte[] image)
{
    int length = 0;
    int offset = 32;
    for(int i=0; i<32; ++i)
    {
        length = (length << 1) | (image[i] & 1);
    }
    byte[] result = new byte[length];
    for(int b=0; b<result.length; ++b )
    {
        for(int i=0; i<8; ++i, ++offset)
            {
            /* I'm getting error at the following line */
            result = (byte)((result << 1) | (image[offset] & 1));
            }
        }
    return result;
}

错误是不兼容的数据类型......需要字节 [] 并找到字节............

Answer 1

您不能对 result 变量进行位移，因为它是一个字节数组。
