NumberFormat getMinimumFractionDigits() method in Java with Examples

The getMinimumFractionDigits() method is a built-in method of the java.text.NumberFormat returns the minimum number of digits allowed in the fraction portion of a number of an instance. Syntax:

public int getMinimumFractionDigits()

Parameters: The function does not accepts any parameter. Return Value: The function returns the minimum number of digits which is allowed in the fraction portion. Below is the implementation of the above function: Program 1: 

Java

// 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 minimum
        int value
            = nF.getMinimumFractionDigits();

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

Output:

The minimum Fraction digits: 0

Program 2: 

Java

// 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 minimum
        int value
            = nF.getMinimumFractionDigits();

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

Output:

The minimum Fraction digits: 2
