Question about the task Multiplication table
Java Syntax, Level 4, Lesson 5
Under discussion
Char instead of String for Space (" ")I suppose using ' ' instead of " " leads to adding an ASCII value of ' ' to my i*j term. Is there any other possibility to tell compiler that I mean Character and not it's ASCII value? Of course I can use String, but it appears to me not that efficient.
