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());    }} |
