Are there existing constant definitions for symbols like $ and €?
such that I could refer to them like:
String myString = SomeClass.DOLLAR_SIGN + myDouble;

Open in new window

Either in Java proper, or another API like Apache Commons.

Maybe all you need to do is something similar to this.  This is pseudocode, but you may be able to get what I mean here.


String myString = char(36) + myDouble;

String myString = char(128) + myDouble;

36 would be $
128 would be €

This function I put in is just something pulled from MS Office, but there probably is something similar in what you are programming with.

Are you able to just simply put "$" + myDouble in your code?

You can use an ENUM:

public enum CurrencyType {
    Pound, Dollar, Lyra, Sheckel }
public class EnumTest {
    Day day;
    
    public CurrType(Currency Type Money) {
        this.Money = Money;
    }
    
    public void MoneyIsFun() {
        switch (Money) {
            case Pound:
                System.out.println("<insert ASCII Symbol here>");
                break;
                    
            case Dollar:
                System.out.println("<insert ASCII Symbol here>");
                break;
                         
            case Lyra: case Sheckel :
                System.out.println("<insert ASCII Symbol here>");
                break;
                        
            default:
                System.out.println("<insert ASCII Symbol here>");
                break;
        }
    }
    
    public static void main(String[] args) {
        EnumTest firstCash = new CurrType(Money.Dollar);
        firstCash.MoneyIsFun();
        EnumTest thirdCash = new CurrType(Money.Pound);
        thirdCash.MoneyIsFun();
        EnumTest fifthCash = new CurrType(Money.Sheckel);
        fifthCash.MoneyIsFun();
        EnumTest sixthCash = new CurrType(Money.Lyra);
        sixthCash.MoneyIsFun();
    }
}

This way you can assign more stuff to it, and do more things.
Hope it helps.
