Java - getting value from an array using string

Question

I need to make an int array using Strings instead of ints. EX: int["number2"] = 0; instead of int[2] = 0;

Does anyone know how to do this?

Thanks for your time.

you could use a HashMap - see here for more info!

Or more generally, any kind of Map.

Java doesn't support associative arrays, but you could use a HashMap:

Map<String, Integer> map = new HashMap<String, Integer>();
map.put("key1", 25);
map.put("key2", 4589);

map.get("key1") will return 25.

You are not looking for an array but for an associative array.

In Java, in practice, every class that implements Map can be used as an associative container, since they can map keys to values (TreeMap<K,V>, HashMap<K,V>, and so on)

This syntax looks very like a map in Groovy, In Java, you could use something like a Map<String, Integer>.
