Well, I’m wanting to name an Array of Strings in Java, but I wanted it to be, for example:

String[] symbols;

And could be declared so:

symbols["name"] = "Tiago";

I know there’s no such Array, but somehow, there’s a way?

You can use the class HashMap to do this.

Example:

Map<String, Integer> vehicles = new HashMap<>();
vehicles.put("BMW", 5);
vehicles.put("Mercedes", 3);
vehicles.put("Audi", 4);
vehicles.put("Ford", 10);

See more about the interface Map, and the class HashMap in:

    That’s right, thanks man, exactly what I needed :D

  • Vinícius, I edited your answer to use Generics and link the javadocs of java 8. Here’s the tip for next time.
