Multi-Language Date Calculator Application in Java

Project Requirements

Project

Submit a zipped archive containing .java file and .doc file with screenshots. Save the .zip in format: .zip (A0123456.zip). The assignment should be submitted through Moodle.Use provided Main.java file to create Java Application which will prompt user for two dates. The application should calculate the difference in-between the dates provided. The feature of this application is multilanguage support. The application should allow user to make more than one calculation, and should exit when user select 0 in language selection. The application should:

• Create menu for user to choose Language

o English, French, German

• Create prompt for user to select Day, Month and Year

o Use provided String arrays with names
o Months and Days are indexed

? January, Janvier and Januar have index 0

• Repeat the prompt twice

o Date from
o Date to

• Dates must be formatted

o Format: "dd MM yyyy"
o Example: "23 01 2021

• Use provided method to calculate difference in days

o int getDaysBetweenTwoDates(String dateString1, String dateString2)
• Print out the answer in selected Language.

• Repeat while languageSelected != 0.
