Java coding assignment custom expandable 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)

The following code works and fulfills the assignment, however apparently my instructor argues that it dosen't complete all the requirements.Bold indicates what my instructor says is missing or I couldn't manage to do.
