hi
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.
thanks

What are you trying to do? Learn about maps, or do verbal arithmetic? If you want verbal arithmetic, you realise that a char is not a letter, but a number, and you can do arithmetic with it?
If you want to learn about Maps, start here.
 
It is sorta covered in the JavaRanch Style Guide.
