Can Java use String as an index array key? (ex: array["a"]=1;)

Question

Can Java use a String as an index array key? Example:

array["a"] = 1; 

Answer 1

No.

To do something like this, you have to use a Map.

Map<String, Integer> aMap = new HashMap<String, Integer>(); aMap.put("a" , Integer.valueOf(1));
