Groovy: variable assignment

I'm about to take a course in computer science and have some decent knowledge in T-SQL and that's it.

The pre reading for this course is not well written. Having trouble how they are getting certain result sets. Here is Groovy statement 

String str
print "Please key in a word: "
str = System.console().readline() 
print "The word was: "
println str

Result 

Please key in a word: Tom
The word was : Tom

Where on earth did they assign or set str = "Tom". I understand variables but have never come across system.console().readLine() so maybe i am missing something? Clearly the pre reading is meant to suggest that I type in value Tom but actually hasn't bothered to show me where.

Regards

Tom

readline() is a method. It does return something. In this case a string.

str = System.console().readline() is an assignment because you use =, the assignment operator.
