NumberFormat getMaximumFractionDigits() method in Java with Examples

The getMaximumFractionDigits() method is a built-in method of the java.text.NumberFormat returns the maximum number of digits allowed in the fraction portion of a number of an instance.

Syntax:

public int getMaximumFractionDigits()

Parameters: The function does not accepts any parameter.

Return Value: The function returns the maximum number of digits which is allowed in the fraction portion.

Below is the implementation of the above function:

Program 1:

// Java program to implement
// the above function

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

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Integer instance
        NumberFormat nF
            = NumberFormat
                  .getIntegerInstance();

        // Stores the maximum
        int value
            = nF.getMaximumFractionDigits();

        // Prints the maximum
        System.out.println("The maximum"
                           + " Fraction digits: "
                           + value);
    }
}

Output:

The maximum Fraction digits: 0

Program 2:

// Java program to implement
// the above function

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

public class Main {
    public static void main(String[] args)
        throws Exception
    {

        // Get the Currency instance
        NumberFormat nF
            = NumberFormat
                  .getCurrencyInstance();

        // Stores the maximum
        int value
            = nF.getMaximumFractionDigits();

        // Prints the maximum
        System.out.println("The maximum"
                           + " Fraction digits: "
                           + value);
    }
}

Output:

The maximum Fraction digits: 2
