Last Updated : 01 Apr, 2019

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
