Program Code – Exploring the World of Java Programming

import java.util.HashMap;
import java.util.Map;
import java.util.Scanner;

public class WorldExplorer {
    private static final Map<String, String> countryCapitals;

    static {
        // Populating our very basic 'world knowledge' database.
        countryCapitals = new HashMap<>();
        countryCapitals.put('India', 'New Delhi');
        countryCapitals.put('Germany', 'Berlin');
        countryCapitals.put('Australia', 'Canberra');
        countryCapitals.put('United States', 'Washington D.C.');
        //... Imagine this list goes on with a decent amount of entries.
    }

    public String fetchCapital(String countryName) {
        // Return the capital if the country is in the database, else return a notice.
        return countryCapitals.getOrDefault(countryName, 'Country not found in our database!');
    }

    public static void main(String[] args) {
        // Kick-off point for the WorldExplorer app
        WorldExplorer worldExplorer = new WorldExplorer();
        Scanner scanner = new Scanner(System.in);
        
        System.out.println('Welcome to the World Explorer!');
        System.out.print('Enter a country name to get its capital: ');
        String userInput = scanner.nextLine();
        
        // Fetching and displaying the capital
        String capital = worldExplorer.fetchCapital(userInput);
        System.out.println('The capital of ' + userInput + ' is: ' + capital);
        
        scanner.close(); // Don't forget to close the scanner!
    }
}

Code Output:

Welcome to the World Explorer!
Enter a country name to get its capital: India
The capital of India is: New Delhi

Code Explanation:

Let’s unpack this bit by bit, shall we?

• We kick things off by importing our necessary packages, HashMap for our nifty little database, and Scanner for reading user input. Kinda like bringing a Swiss army knife on a world trek!
• Up next, we introduce WorldExplorer to the scene. You know, our prodigy class that knows all about capitals? It’s practically screaming for attention with its shiny public access modifier.
• We stash some nuggets of knowledge in countryCapitals, a static block that laces our boots with capital-city know-how before we even take our first step!
• fetchCapital is like that smarty-pants friend who always has the answers. Give it a country name, and bam, it digs into its brainy countryCapitals to find you answers like a pro.
• Inside main, we stir things up by creating an instance of WorldExplorer. It’s like saying ‘Hello, World!’ but in a more globe-trotting way.
• Then, we introduce Scanner, our trusty sidekick, ready to capture user inputs like a dream. We prompt the user for the country name because, of course, we can’t read minds.
• With the country name secure, we embark on a mini-quest to fetchCapital. It’s basically our own version of ‘Who Wants to Be a Millionaire?’ but with less drama.
• Finally, we print out the result, waving it high like the flag of victory, and tie up loose ends by telling our Scanner to cool its jets (scanner.close()).

So, what we’ve got here is a nifty little code snippet that puts ‘worldly smart’ in your pocket. Remember to dream big and code on, folks! 👩‍💻✨
