Using java.util.Scanner to read a file byte by byte?

That's like using a wheelbarrow to transport your pocket change. (If you really need a wheelbarrow for your pocket change, let me know so I can become your friend).

That's like using a wheelbarrow to transport your pocket change. (If you really need a wheelbarrow for your pocket change, let me know so I can become your friend). But seriously: Class InputStream reads bytes from a file, simply and reliably, and does nothing else.

Class scanner was recently introduced into the Java API so textbook examples could pull data out of a file with less pain than is usually involved with using the cascade of new BufferedReader(new InputStream). Its specialty is inputting numbers and strings from free-form input files. The nextByte() method actually reads one or a few decimal digits from the input stream (if they're there) and converts the number thus scanned into a single byte value.

And if you're reading bytes, why do you want to output them as chars? Bytes are not chars, and brute-force interconverting will fail in some places. If you want to see the values of those bytes, print them out as they are and you'll see small integers between 0 and 255.

If you want to read chars from a file, FileReader is the class for you.

Scanner is for parsing text data - its nextByte() method expects the input to consist of digits (possibly preceded by a sign). You probably want to use a FileReader if you're actually reading text data, or a FileInputStream if it's binary data. Or a FileInputStream wrapped in an InputStreamReader if you're reading text with a specific character encoding (unfortunately, FileReader does not allow you to specify the encoding but uses the platform default encoding implicitly, which is often not good).

When troubleshooting Scanner, check for underlying I/O errors: if(scanner.ioException()! = null) { throw scanner.ioException(); } Though I'm with the others - this probably isn't the right class for the job. If you want byte input, use an InputStream (in this case, FileInputStream).

If you want char input, use a Reader (e.g. InputStreamReader).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
