byte array to unsigned int in java

Question

I\'m converting a byte array into int by doing this:

ByteArrayInputStream bais = new ByteArrayInputStream (data);
DataInputStream dis = new Data         


        

Answer 1

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
    int res = 0;
    if (bytes == null)
        return res;

    for (int i = 0; i < bytes.length; i++) {
        res = (res *10) + ((bytes[i] & 0xff));
    }
    return res;
}

• The code will convert [12,34] to 1234
