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
