The hashCode() Method of DateFormat class is used to return the hash code value of this DateFormat 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 DateFormat object and is of integer type.
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
