[Bluej-discuss] asking for help

[John Simonds]

Exercise 5.7 asks the student to find the trim method in the Java Class libraries documentation (this I did).  Then it asks what "the documentation says about control charachters at the beginnig of a string."  
I could not make heads or tails of what it said, since it went on about "Unicode charachters," 
(which it does not elaborate as to what that means) and some obscure formula which does nothing to explain what to do with control charachters, and what are control charachters?
I don't see this exercise as being very well defined.  Could anyone clear this up?
