#Code not working as intended

Hello, this is a simplified version of code that I'm working on for a school project. This is meant to be a Chess-related program. To briefly explain what this snippet is supposed to do, it is supposed to ask what specific square any piece is on, and the program is simply supposed to return whether that square exists or not, based on hashmapped int values going from 1 to 64 (since there is 64 squares on a chess board). However, whenever I DO input a valid square option (such as "c1" for example), it claims that the square does not exist, even though it's supposed to match a value in the Hashmap. I simply cannot find the problem. (btw I'm a bit of a Java noob)

ohhhhh, I see. That else statement is not being used correctly then, yes?

glacial patio

yeah you probably don't want that there

#

Also is there a reason as to why you're using a HashMap rather than an ArrayList

Well I'm not sure. All I really need is for those specific numbers to represent its respective square (so 1 MUST be a1, 64 MUST be h8, etc.,). But should an ArrayList be able to do this better? I might switch it to that if so.

They're 0 indexed so 0 will be A1 but that's easily fixable by adding one to the output

#

or subtracting one from the input

Okay then, this was very helpful. Thank You!
