Generate new Variables in java

Question

I'd like to automaticly create a new Variable for my Storage.

It should work like:

int var_count = getConfig().getInt("var_count");
++var_count;

int "var"+var_count = 123

If var_count is for example 4, it should generate a Variable named var4.

Is there a certain thing that you're trying to do with this? It is possible that a structure such as a List or Map would be more suited to what you're trying to do. — Daniel Underwood, Jan 03 '16 at 22:54

You can't. You could (however) make a Map<String, Integer> and store arbitrary key-value pairs. Something like

Map<String, Integer> map = new HashMap<>();
map.put("var" + var_count, 123);
System.out.println(map.get("var" + var_count));
