The setGroupingUsed() method is a built-in method of the java.text.NumberFormat which sets the grouping to be used.
Syntax:
public void setGroupingUsed(boolean val)
Parameters: The function accepts a mandatory parameter val which specifies the grouping 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:
// 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
{
NumberFormat nF
= NumberFormat.getNumberInstance();
System.out.println( "Grouping set initially as: "
+ nF.isGroupingUsed());
// Set grouping
nF.setGroupingUsed( false );
// Print the currency
System.out.println( "Grouping set finally as: "
+ nF.isGroupingUsed());
}
} |
Output:
Grouping set initially as: true Grouping set finally as: false
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
{
NumberFormat nF
= NumberFormat.getNumberInstance();
System.out.println( "Grouping set initially as: "
+ nF.isGroupingUsed());
// Set grouping
nF.setGroupingUsed( true );
// Print the currency
System.out.println( "Grouping set finally as: "
+ nF.isGroupingUsed());
}
} |
Output:
Grouping set initially as: true Grouping set finally as: true
