DecimalFormat hashCode() method in Java

The hashCode() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to get an integral hashCode value for this DecimalFormat instance.

Syntax:

public int hashCode()

Parameters: The function does not accepts any parameter.

Return Value: The function returns an integral hashCode value.

Below is the implementation of the above function:

Program 1:

// Java program to illustrate the
// hashCode() 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 hashCode value
        System.out.println(deciFormat.hashCode());
    }
}

Output:

423132

Program 2:

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

import java.text.DecimalFormat;
import java.util.Currency;
import java.util.Locale;
import java.math.RoundingMode;

public class Main {
    public static void main(String[] args)
    {

        // Create the DecimalFormat Instance
        DecimalFormat deciFormat = new DecimalFormat();
        deciFormat.getInstance(Locale.US);

        // Print the hashCode Value
        System.out.println(deciFormat.hashCode());
    }
}

Output:

423132
