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
