I test it by entering the usual test string “Hello World,” which prints fine. Then “Hello” with
one space, and the space is deleted. With five spaces, exactly the five spaces go. With six or
more spaces, only five spaces go. A blank line comes out as a blank line (i.e., without throw-
ing an
Exception
or otherwise going berserk). I think it works!

Entering Nonprintable Characters
Problem
You need to put nonprintable characters into strings.
Solution
Use the backslash character and one of the Java string escapes.
