The getMaximumIntegerDigits() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to get the maximum 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 getMaximumIntegerDigits()

Parameters: The function does not accepts any parameter.

Return Value: The function returns the maximum 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
// getMaximumIntegerDigits() 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 Maximum Integral digits allowed
        System.out.println(deciFormat.getMaximumIntegerDigits());
    }
}

Output:

2147483647

Program 2:




// Java program to illustrate the
// getMaximumIntegerDigits() 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 Maximum Integral digits allowed
        System.out.println(deciFormat.getMaximumIntegerDigits());
    }
}

Output:

2147483647
