The assignment consists of “Basic Requirements” and “Additional Requirements” as described in sections 3 and 4 respectively. You MUST complete the basic requirements BEFORE proceeding with the additional requirements.
For this assignment, you are expected to do the following :
• carry out proper problem analysis and program design before you start coding your program;
• break your program into smaller and simpler parts;
• implement and test a part at a time;
• use methods where appropriate.
The required resources for this assignment are:
J2se 1. 5 (or higher version)
JGrasp 1.8.5 (or higher version)
3. BASIC REQUIREMENTS
The system should provide the following basic features:
● Display result
To allow the user to view all the countries and their medals
● Enter the result
To allow the user to update the result each time an event has completed
● Display countries which have achieved a given number of gold medals
To allow the user to view the countries which have achieved a given number of gold medals
● Find the country with the most gold medals
To allow the user to view the country with the highest number of gold medals
● Find the country with the least gold medals
To allow the user to view the country with the lowest number of gold medals
● Validation (and feedback)
The program should handle all invalid entries by the user, e.g. invalid numeric data. If user made a mistake in the entry, the program should inform the user via appropriate feedback.
Please refer to the sample screen-shots below for more details
