DecimalFormat getMinimumIntegerDigits() method in Java

Last Updated : 01 Apr, 2019

The getMinimumIntegerDigits() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to get the minimum number of digits allowed in the integral part of a Number. The integral part in a number is defined as the part present before the decimal point ( . ). For example, in the number 123, 45.678, the integral part is 123, 45. Syntax:

public int getMinimumIntegerDigits()

Parameters: The function does not accepts any parameter. Return Value: The function returns the minimum number of digits allowed in the integral part of a number. Below is the implementation of the above function: Program 1:

// Java program to illustrate the
// getMinimumIntegerDigits() method

import java.text.DecimalFormat;
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();

        // Print the minimum Integral digits allowed
        System.out.println(deciFormat.getMinimumIntegerDigits());
    }
}

 
// Java program to illustrate the
// getMinimumIntegerDigits() method​import java.text.DecimalFormat;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();​        // Print the minimum Integral digits allowed        System.out.println(deciFormat.getMinimumIntegerDigits());    }}

Output:

Program 2:

// Java program to illustrate the
// getMinimumIntegerDigits() method

import java.text.DecimalFormat;
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.applyPattern("##.##");

        // Print the Minimum Integral digits allowed
        System.out.println(deciFormat.getMinimumIntegerDigits());
    }
}
