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
