This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I am extreme newbie. I'd like to read in multiple lines and create a two-dimensional array from them. I am using Groovy/Grails with Intellij. Can you show me how to create/update a two-dimentsional character array?
