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 was wondering if someone could give me a hand and show me how can I use the util.scanner and hashmaps to assign values to keys get the user type 2 keys and get the return sum of the value of these two keys. for example
A = 1
B = 2
C = 3
D = 4
the user will use util.scanner to type any letter from A to D and the compiled will give him the sum of these letters
your help will be gladlyyyy appreciated.
