    Default Re: variable declaration

    Identifiers don't exist at runtime, so you can't manipulate them with your code. Try using a HashMap instead.

    Java Code:
    HashMap<String, Integer> hm = new HashMap<String, Integer>();
    hm.put("foo", 7);
    hm.put("bar", -8886);
    System.out.println(hm.get("foo")); // prints 7
