To pass all tests, Java 8 must be used.

import java.util.; import java.text.;

public class Solution {

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

    // US Locale
    NumberFormat us = NumberFormat.getCurrencyInstance(Locale.US);

    // India Locale (custom, because no built-in Locale)
    Locale indiaLocale = new Locale("en", "IN");
    NumberFormat india = NumberFormat.getCurrencyInstance(indiaLocale);

    // China Locale
    NumberFormat china = NumberFormat.getCurrencyInstance(Locale.CHINA);

    // France Locale
    NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);

    System.out.println("US: " + us.format(payment));
    System.out.println("India: " + india.format(payment));
    System.out.println("China: " + china.format(payment));
    System.out.println("France: " + france.format(payment));
}

}

just run in Java 7 to pass all the testcases otherwise in java 15 it won't pass even you output is exactly the same, even if you try changing the encodings.
