Reading file data that contains no spaces

[jdepue]

Understand that you use token to read the next word/number of a file using delimiters. How do you read data from a file with no spaces and break it up by number of characters?

Is this actual character data you are reading or binary data?
If it is character data use a FileReader to read a character at a time out of the file.
If it is binary data use a FileInputStream to read a byte at a time.

both have the option to read data into either a char[] or a byte[], respectively. This way you can read chunks of the file at a time.
