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
