2. Common Methods

• getInstance(String currencyCode): Returns the Currency instance for the specified currency code.
• getInstance(Locale locale): Returns the Currency instance for the specified locale.
• getCurrencyCode(): Returns the ISO 4217 currency code of the currency.
• getSymbol(): Returns the symbol of the currency for the default locale.
• getSymbol(Locale locale): Returns the symbol of the currency for the specified locale.
• getDefaultFractionDigits(): Returns the number of fractional digits used by the currency.

3. Examples of Using the Currency Class

Example 1: Getting Currency by Code

This example demonstrates how to get a Currency instance using a currency code.

        System.out.println("Currency Symbol: " + currency.getSymbol());
        System.out.println("Fraction Digits: " + currency.getDefaultFractionDigits());
    }
}
