Java HashMap associative multi dimensional array can not create or add elements

Question

Okay so I have spent several hours trying to wrap my head around this concept of a HashMap in Java but am just not able to figure it out. I have looked at many tutorials but

Answer 1

HashMap> myArray = new HashMap>();

if (!myArray.containsKey("en")) {
    myArray.put("en", new HashMap());
}
myArray.get("en").put("name", "english name");

In Java you have to be explicit about when you are creating an object. In this case first we check if there is already a HashMap object stored in our outer HashMap under the key "en". If not, we create an empty one.

Now to put a new value into it we have to first get it from the outer HashMap, then put the new value.
