Question

我需要将欧元或英镑符号分配给变量.我怎样才能做到这一点？

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

Answer 1

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);
    }
}

Answer 2

如果您无法输入,那么您可以使用欧元的unicode值:

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

但是,如果你这样做,最佳做法是对其进行注释和/或将其保存为常量字段以便清晰(代码中无法解释的unicode文字只是简单的混淆!):

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

Answer 3

public final static char EURO = '\u20ac';
