原文:https://www . geesforgeks . org/currency-getsymbol-method-in-Java-with-examples/

Java 中 Currency 类的 getSymbol() 方法用于检索货币代码的官方符号。

语法:

CURRENCY.getSymbol()

参数:此方法不接受任何参数。

返回值:此方法返回货币的官方符号。

异常:如果调用了无效代码，该方法将抛出运行时错误。

下面的程序说明了 getSymbol()方法的工作原理:

程序 1:

// Java Code to illustrate getSymbol() method

import java.util.*;

public class Currency_Demo {
    public static void main(String[] args)
    {

        // Creating a currency with the code
        Currency curr_ency
            = Currency.getInstance("INR");

        // Getting the symbol of the currency
        String currency_symbol
            = curr_ency.getSymbol();
        System.out.println("Symbol for the currency of India is: "
                           + currency_symbol);
    }
}

Output:

Symbol for the currency of India is: INR

程序 2:

// Java Code to illustrate getSymbol() method

import java.util.*;

public class Currency_Demo {
    public static void main(String[] args)
    {

        // Creating a currency with the code
        Currency curr_ency
            = Currency.getInstance("USD");

        // Getting the symbol of the currency
        String currency_symbol
            = curr_ency.getSymbol();
        System.out.println("Symbol for the currency of USA is: "
                           + currency_symbol);
    }
}

Output:

Symbol for the currency of USA is: $

程序 3: 为无效的货币代码。

// Java Code to illustrate getSymbol() method

import java.util.*;

public class Currency_Demo {
    public static void main(String[] args)
    {
        try {

            // Creating a currency with the code
            Currency curr_ency
                = Currency.getInstance("USDA");

            // Getting the symbol of the currency
            String currency_symbol
                = curr_ency.getSymbol();
            System.out.println("Symbol for the currency of USA is: "
                               + currency_symbol);
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

java.lang.IllegalArgumentException
