DecimalFormat toLocalizedPattern() method in Java

The toLocalizedPattern() method of the DecimalFormat class in Java is used to convert the format of the current pattern of this DecimalFormat to a localized string format. This converted localized string represents the pattern which is used to format the current state of this DecimalFormat instance.

Syntax:

public String toLocalizedPattern()

Parameters: This method does not accepts any parameter.

Return Value: This method returns a localized string which represents the pattern which is used to format the current state of this DecimalFormat instance.

Below programs illustrate the above method:

Program 1:

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

import java.text.DecimalFormat;

public class GFG {

    public static void main(String[] args)
    {

        // Create a DecimalFormat instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Convert the current formatting state
        // to a string object
        String pattern = deciFormat.toLocalizedPattern();

        System.out.println(pattern);
    }
}

Output:

#, ##0.###

Program 2:

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

import java.text.DecimalFormat;

public class GFG {

    public static void main(String[] args)
    {

        // Create a DecimalFormat instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Apply a new pattern
        deciFormat.applyPattern("##, ##.##");

        // Convert the current formatting state
        // to a string object
        String pattern = deciFormat.toLocalizedPattern();

        System.out.println(pattern);
    }
}

Output:

#, #0.## ;#, #0.##
