Below programs illustrate the working of hashCode() Method of SimpleDateFormat:

Example 1:

// Java to illustrate hashCode() method

import java.text.*;
import java.util.*;

public class SimpleDateFormat_Demo {
    public static void main(String[] args)
        throws InterruptedException
    {
        // Initializing SimpleDateFormat
        SimpleDateFormat SDFormat
            = new SimpleDateFormat(
                "dd/MM/yyyy");

        // Displaying the formats
        Date date = new Date();
        String str_Date1 = SDFormat.format(date);
        System.out.println("The Original: "
                           + (str_Date1));

        // Displaying the hash code
        System.out.println("The hash code: "
                           + SDFormat.hashCode());
    }
}

Output:

The Original: 30/01/2019
The hash code: -650712384

Example 2:

// Java to illustrate hashCode() method

import java.text.*;
import java.util.*;

public class SimpleDateFormat_Demo {
    public static void main(String[] args)
        throws InterruptedException
    {
        // Initializing SimpleDateFormat
        SimpleDateFormat SDFormat
            = new SimpleDateFormat(
                "MM/dd/yyyy");

        // Displaying the formats
        Date date = new Date();
        String str_Date1 = SDFormat.format(date);
        System.out.println("The Original: "
                           + (str_Date1));

        // Displaying the hash code
        System.out.println("The hash code: "
                           + SDFormat.hashCode());
    }
}

Output:

The Original: 01/30/2019
The hash code: 2087096576
