This Answer Works in JAVA 8 :

import java.text.NumberFormat; import java.util.Locale; import java.util.Scanner;

public class CurrencyFormatter { public static void main(String[] args) { Scanner sc = new Scanner(System.in); // Read input double payment = sc.nextDouble(); // For example, we use a fixed number. In actual use, this could be read from input.

    // US Locale
    Locale us = Locale.US;
    NumberFormat usFormat = NumberFormat.getCurrencyInstance(us);
    String usFormatted = usFormat.format(payment);

    // India Locale
    Locale india = new Locale("en", "IN");
    NumberFormat indiaFormat = NumberFormat.getCurrencyInstance(india);
    String indiaFormatted = indiaFormat.format(payment);

    // China Locale
    Locale china = Locale.CHINA;
    NumberFormat chinaFormat = NumberFormat.getCurrencyInstance(china);
    String chinaFormatted = chinaFormat.format(payment);

    // France Locale
    Locale france = Locale.FRANCE;
    NumberFormat franceFormat = NumberFormat.getCurrencyInstance(france);
    String franceFormatted = franceFormat.format(payment);

    // Print results
    System.out.println("US: " + usFormatted);
    System.out.println("India: " + indiaFormatted);
    System.out.println("China: " + chinaFormatted);
    System.out.println("France: " + franceFormatted);
}

}

I wasted too much time in this problem. Still couldn't find the solution. May be better to focus on other problems.

This is so broken, don't bother doing in anything other then java 8. i think this question need changing for each verstion. this was every furstrating as i wasted 20 miuntes undering why my correct answer was wrong, even after changing the China: ¥ to the China: ￥ and the India: Rs.

I got my submission to pass by switching to Java 8 from java 15. But I left my workarounds for some of the problems. HackerRank shoul have different answers for the different Java versions, like they do with different SQL varieties.

Three differences: * Java 15 uses the Rupee symbol, but the answer wanted "Rm.". Had to create a custom currency fix for that. * Java 15 uses a different "Yen"/"Yuan" symbol than Java 8. * Java 15 uses a "NARROW NO-BREAK SPACE" (U+202F) code point for the grouping/thousands chaSPracter. The answer used a regular space character SPACE (U+0020).

This solution passes validation for Java 8

public class Solution {
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double payment = scanner.nextDouble();
        scanner.close();

        // Create NumberFormat instances for each required locale
        NumberFormat usFormat = NumberFormat.getCurrencyInstance(Locale.US);
        NumberFormat indiaFormat = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));
        NumberFormat chinaFormat = NumberFormat.getCurrencyInstance(Locale.CHINA);
        NumberFormat franceFormat = NumberFormat.getCurrencyInstance(Locale.FRANCE);

        // Format the payment value according to each locale
        String us = usFormat.format(payment);
        String india = indiaFormat.format(payment);
        String china = chinaFormat.format(payment);
        String france = franceFormat.format(payment);

        // Print each formatted currency value
        System.out.println("US: " + us);
        System.out.println("India: " + india);
        System.out.println("China: " + china);
        System.out.println("France: " + france);
        
}
}
