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

Unfortunately, there's no concise syntax for constructing populated maps in Java. You'll have to write it out long-hand. A separate helper method can make it a little simpler:

HashMap makeMap(String name, String desc, String keys) {
    HashMap map = new HashMap<>();
    // Before Java 7, above must be: new HashMap();
    map.put("name", name);
    map.put("desc", desc);
    map.put("keys", keys);
}

Then:

HashMap> myArray = new HashMap<>();
myArray.put("en",
    makeMap("english name", "english description", "english keywords"));
// etc.

You would retrieve it with:

english_name = myArray.get("en").get("name");
