Question

I am new in Stack Exchange, and I have been looking around for quite a while, with no answer. In my free time I am creating a matlab/like program in Java, I have noticed that I need to create a way of allowing the user to create its own variables from within the program. An example would be a = 5 and b = 3, and so when a + b = 8.
My first idea was to create a folder, where files can be saved as variables and then searched when the user calls for a particular variable. Any kind of feedback would be greatly appreciated. Thank you!

Answer 1

Simply you could do this using Map

Map<String, Integer> nameToValueMap

• Ask user about name and put its value into map
• Ask user to add two variables (lets say A, B) , fetch the associated values from map and manipulate it
