The setMaximumFractionDigits() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to set the maximum number of digits allowed in the fractional part of a number. The fractional part of a number is the part displayed after the decimal(.) symbol.
Syntax:
public void setMaximumFractionDigits(int newVal)
Parameters: The function accepts a single parameter newVal which is the new value for the maximum number of fractional digits allowed to be set for this DecimalFormat instance.
Return Value: The function does not returns any value.
Below is the implementation of the above function:
Program 1:
// Java program to illustrate the// setMaximumFractionDigits() method  import java.text.DecimalFormat;import java.text.DecimalFormatSymbols;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.setMaximumFractionDigits(6);          System.out.println(deciFormat.format(12.3456789));    }} |
Output:
12.345679
Program 2:
// Java program to illustrate the// setMaximumFractionDigits() method  import java.text.DecimalFormat;import java.text.DecimalFormatSymbols;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.setMaximumFractionDigits(1);          System.out.println(deciFormat.format(12.3456789));    }} |
Output:
12.3
