[UNANSWERED ]Using value as variable

Question

How can I use a string as a variable name?
I want sth like that:
String str = "var";
int (str) = 6;

Answer 1

The best way is using a java.util.HashMap like so:

HashMap<String,Integer> variables = new HashMap<>();
String str = "var";
variables.put (str, 6); // set up
variables.get(str); // get value
