How can I assign the Euro or the Pound symbol to a variable?

I need to assign 开发者_开发百科the Euro or the Pound symbol to a variable. How can i do this?

String euro = "";// What i have to write here??
System.out.println(euro);// I need to print euro symbol

public class ExampleEuroPound {

    public static void main(String args[]){

        String euro = "\u20ac";
        String pound = "\u00a3";

        System.out.println("pound = " + pound);
        System.out.println("euro = " + euro);
    }
}

If you can't type it then you could use the unicode value for euro:

String euro = "\u20AC";
System.out.println(euro);

If you're doing this however, best practice is to comment it and / or save it as a constant field for clarity (unexplained unicode literals in code are just plain confusing!):

public static final String POUND = "\u00A3";
public static final String EURO = "\u20AC";

public final static char EURO = '\u20ac';

I'd wonder if you'd be better off using the currency formatter for numbers in the java.text package. IF there's ever a chance that you'd want to use something other than euro, based on locale, this would be a better choice.

You might also think about a Money class. I think you need a better abstraction than mere Strings or doubles for programs that involve cash.

There are two ways:

• Type or copy/paste the Euro/Pound symbol into your source code. This requires the editor/IDE to support these characters (typically not a problem) and to use an encoding that does (potentially a problem), and for the compiler to use the same encoding (potentially a problem). Overall, this is risky since it can break whenever something in the development or build environment changes.
• Use a unicode escape sequence in the source code: \u20AC is the Euro sign, \u00A3 the Pound sign.

What would be the point of doing

String euro = "€";

You should do it like this:

String euro = "\u20AC";
