Java currency format

In Java, you can use the NumberFormat class from the java.text package to format numbers as currency values.

Here is an example of how to use the NumberFormat class to format a number as a currency value in Java:

import java.text.NumberFormat;
import java.util.Locale;

public class Main {
  public static void main(String[] args) {
    // Create a NumberFormat instance for the US locale
    NumberFormat formatter = NumberFormat.getCurrencyInstance(Locale.US);

    // Format a number as a currency value
    double amount = 123.45;
    String formattedAmount = formatter.format(amount);

    // Print the formatted currency value
    System.out.println(formattedAmount);  // Output: $123.45
  }
}

In this example, we create a NumberFormat instance for the US locale using the NumberFormat.getCurrencyInstance method. We then call the format method on the NumberFormat instance to format the number 123.45 as a currency value. The format method returns a string representation of the formatted currency value.

You can also use the NumberFormat class to format currency values for other locales. For example, you can use the Locale.FRANCE constant to create a NumberFormat instance for the French locale, or the `Locale.
