Is there an associative array type data structure in Java?

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

String[] symbols;

And that could be stated like this: 

symbols["name"] = "Tiago";

I know that Array does not exist like this, but in some other way, how?

You can use the HashMap class 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 interface Map , and class HashMap on:
