The setMinimumIntegerDigits() method is a built-in method of the java.text.NumberFormat which sets the minimum number of digits allowed in the integer portion of a number. If the new value for minimumIntegerDigits is less than the current value of maximumIntegerDigits, then maximumIntegerDigits will also be set to the new value.
Syntax:
public void setMinimumIntegerDigits(int val)
Parameters: The function accepts a mandatory parameter val which specifies the minimum 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:
// 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("Minimum set initially as: "                           + nF.getMinimumIntegerDigits());          // Set grouping        nF.setMinimumIntegerDigits(100);          // Print the final        System.out.println("Minimum set finally as: "                           + nF.getMinimumIntegerDigits());    }} |
Output:
Minimum set initially as: 1 Minimum set finally as: 100
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("Minimum set initially as: "                           + nF.getMinimumIntegerDigits());          // Set grouping        nF.setMinimumIntegerDigits(1);          // Print the final        System.out.println("Minimum set finally as: "                           + nF.getMinimumIntegerDigits());    }} |
Output:
Minimum set initially as: 1 Minimum set finally as: 1
