Question

Modification of original code so it can include 1) at least one array 2)*New English words that are written/saved to the .txt file(s) must be in alphabetical order* (e.g, Apple cannot be in a lower line than Orange). This is what I'm really struggling with as I don't know how to organize alphabetically only the english word translation without the spanish equivalent word also getting organized.

The only idea I have right now is to recreate the code using two dimensional arrays, but I don't if that would fulfill the purpose

Further explanation of the code at the end if needed.

The main goal of the code is to create an expandable custom translator. When program starts 1) ask user if they want to add or look up a word

Add a word option: 1) ask for English word version 2) Then ask for other language word version 3) *New words that are written to the english .txt file must be in alphabetical order* (e.g, Apple cannot be in a lower line than Orange) 4) Any method to store data in file (e.g., one data.txt file or more)

Look up a word option: 1) ask which language the user wants to start with 2) Ask for word entry 3) Program should find the equivalent word in the other language

Code requirements: At least one array, use of user input, save or read files from a text file(s) , a loop, an conditional statement, exception handling, Appropriate object classes that encapsulate some program logic (User Defined Object-Oriented Solution appropriate object classes that encapsulate some program logic).

Answer 1

Implementation in java using a 2d array as per the requirement and performing all the read and write operations to a text file. Also, the words in the dictionary are stored in sorted/ lexicographical order
