The setMaximumFractionDigits() method is a built-in method of the java.text.NumberFormat which sets the maximum number of digits allowed in the fraction portion of a number.If the new value for maximumFractionDigits is less than the current value of minimumFractionDigits, then minimumFractionDigits will also be set to the new value.
Syntax:
public void setMaximumFractionDigits(int val)
Parameters: The function accepts a mandatory parameter val which specifies the maximum value to be set.
Return Value: The function returns nothing, hence has a return type void.
Below is the implementation of the above function:
Program 1:
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
public class Main {
public static void main(String[] args)
throws Exception
{
NumberFormat nF
= NumberFormat.getNumberInstance();
System.out.println( "Maximum set initially as: "
+ nF.getMaximumFractionDigits());
nF.setMaximumFractionDigits( 100 );
System.out.println( "Maximum set finally as: "
+ nF.getMaximumFractionDigits());
}
}
|
Output:
Maximum set initially as: 3
Maximum set finally as: 100
Program 2:
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
public class Main {
public static void main(String[] args)
throws Exception
{
NumberFormat nF
= NumberFormat.getNumberInstance();
System.out.println( "Maximum set initially as: "
+ nF.getMaximumFractionDigits());
nF.setMaximumFractionDigits( 6785 );
System.out.println( "Maximum set finally as: "
+ nF.getMaximumFractionDigits());
}
}
|
Output:
Maximum set initially as: 3
Maximum set finally as: 6785
