The hashCode() Method of SimpleDateFormat class is used to return the hash code value of this SimpleDateFormat object. The hash code is of integer type.
Syntax:
public int hashCode()
Parameters: The method does not take any parameters.
Return Value: The method returns the hash code value of this SimpleDateFormat object and is of integer type.
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
