Answer 1

For someone looking out there to convert a given digit in human readable form.

public static String getHumanReadablePriceFromNumber(long number){

    if(number >= 1000000000){
        return String.format("%.2fB", number/ 1000000000.0);
    }

    if(number >= 1000000){
        return String.format("%.2fM", number/ 1000000.0);
    }

    if(number >= 100000){
        return String.format("%.2fL", number/ 100000.0);
    }

    if(number >=1000){
        return String.format("%.2fK", number/ 1000.0);
    }
    return String.valueOf(number);

}

For now, you should use ICU's CompactDecimalFormat, which will localize the formatting result for non-english locales. Other locales might not use a "Millions" suffix.

This functionality will be standard Java in JDK 12 with CompactNumberFormat.
