如何从Java的扫描仪中提取单个字符？

Question

What all I want to do is extract a single character every time from a text file, no matter it is a whitespace and/or new line character, till the eof. Would using ""(empty string) as a delimiter work?

scanner.next().charAt[0]

The above code will take the first character of the string returned by

scanner.next()

and ignore the rest of the part. But I want just a single character every time from a file without ignoring any.

if you want to read a file character by character, use a Reader, not a Scanner. A Scanner is for "scanning" for specific patterns.
