How to create a variable with a user-defined name in Java?

Multi tool use
How would one create a new object in Java using a variable name provided by the user?

Use a Map<String, Object>
where you use the user input (in this case, "Hello"
) as the key and the desired object as value.
Classy solution.

What you are trying to do is dynamically create variables at runtime. This unfortunately is not possible to do in java.
There are alternative ways to go about this. More info here: Is it possible to create variables at runtime in Java?
