Question

We are hired to implement an interactive dictionary. Our dictionary takes input from users and uses the input as search key to look up values associated with the key. Requirements:

Coding: No hard coding, https://en.wikipedia.org/wiki/Hard_coding . - Data Source: Store the original data in a set of enum objects. Each keyword, each part of speech, and each definition must be stored in a separate data field. Do not combine them such as storing three parts in one String.

Data Structure: Use existing data structure(s) or creating new data structure(s) to store our dictionary’s data. -

Data Loading: When our program starts, it loads all the original data from the enum objects into our dictionary’s data structure.

User Interface: A program interface allows users to input search keys and displays returned results. Our program searches the dictionary’s data (not the enum objects) for values associated with the search keys.

- Identical Output: Our program’s output must be identical to the complete sample run’s output. The complete output is at:
