Многомерный HashMap с внутренними картами Stream ⇐ JAVA

[Anonymous]

При изучении HashMaps
хеш-карта имеет 4 внутренние карты Integer и одну для CustomObject.
Для многомерной хэш-карты с 6 столбцами: Я пытаюсь создать метод Streams, который, если я введу ключ, вернет значение из одной из 4 внутренних карт.
В черновой форме метод называется Profiler_Processor. Спасибо!
