Below programs illustrate the working of hashCode() Method of DateFormat:
Example 1:

// Java to illustrate hashCode() method 
  
import java.text.*; 
import java.util.*; 
  
public class DateFormat_Demo { 
    public static void main(String[] args) 
    { 
        // Initializing DateFormat 
        DateFormat DFormat 
            = DateFormat.getDateTimeInstance(); 
  
        // Displaying the formats 
        Date date = new Date(); 
        String str_Date1 = DFormat.format(date); 
        System.out.println("The Original: "
                           + (str_Date1)); 
  
        // Displaying the hash code 
        System.out.println("The hash code: "
                           + DFormat.hashCode()); 
    } 
} 

Output:

The Original: Mar 27, 2019 10:20:51 AM
The hash code: 2034585966

Example 2:

// Java to illustrate hashCode() method 
  
import java.text.*; 
import java.util.*; 
  
public class DateFormat_Demo { 
    public static void main(String[] args) 
    { 
        // Initializing DateFormat 
        DateFormat DFormat 
            = new SimpleDateFormat("MM/dd/yyyy"); 
  
        // Displaying the formats 
        Date date = new Date(); 
        String str_Date1 = DFormat.format(date); 
        System.out.println("The Original: "
                           + (str_Date1)); 
  
        // Displaying the hash code 
        System.out.println("The hash code: "
                           + DFormat.hashCode()); 
    } 
} 

Output:

The Original: 03/27/2019
The hash code: 2087096576
