DecimalFormat getMaximumFractionDigits() method in Java

The getMaximumFractionDigits() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to get the maximum number of digits allowed in the fractional or the decimal part of a Number.

Syntax:

public int getMaximumFractionDigits()

Parameters: The function does not accepts any parameter.

Return Value: The function returns the maximum number of digits allowed in the decimal part of a number.

Below is the implementation of the above function:

Program 1:

// Java program to illustrate the
// getMaximumFractionDigits() method

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

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

        // Create the DecimalFormat Instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Print the Grouping Size
        System.out.println(deciFormat.getMaximumFractionDigits());
    }
}

Output:

3

Program 2:

// Java program to illustrate the
// getMaximumFractionDigits() method

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

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

        // Create the DecimalFormat Instance
        DecimalFormat deciFormat = new DecimalFormat();
        deciFormat.applyPattern("##.##");

        // Print the Grouping Size
        System.out.println(deciFormat.getMaximumFractionDigits());
    }
}

Output:

2
