Backstory
Since I am currently in the process of self-teaching Arabic, I thought this project would be a good idea. It has allowed me to combine two of my hobbies: languages and programming, and overall, it has been a very enjoyable experience. Being new to Java, this project has enabled me to explore more complex programming features such as JUnit testing, encapsulation, inheritance, polymorphism, etc. Additionally, I’ve had the opportunity to learn some more Arabic words. A definite win-win!
Brief Overview
This project can be broken down into four main components.
A signup feature that validates inputted information, maintains data integrity by avoiding duplicates, and securely stores user data for future access. This data is crucial not only for logins but also for populating leaderboards and tracking XP progression.
Flashcards that display the word, its Arabic spelling, phonetic pronunciation, English translation, and audible pronunciation.
Arabic listening exams where users listen to a word and write its English meaning. Successful completion allows progression to more challenging modes, currently categorised as beginner, intermediate, and advanced
A global leaderboard featuring an XP system where users earn XP by completing tests and studying flashcards.
