The hashCode() method of java.time.chrono.JapaneseDate class is used to get the hash code for the particular japanese date.
Syntax:
public int hashCode()
Parameter: This method does not accept any argument as a parameter.
Return Value: This method returns the hash code for the particular japanese date.
Below are the examples to illustrate the hashCode() method:
Example 1:
// Java program to demonstrate // hashCode() method import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// JapaneseDate Object
JapaneseDate hidate = JapaneseDate.now();
// getting hash code of the date
// by using hashCode() method
long tempo = hidate.hashCode();
// display the result
System.out.println( "hashcode : "
+ tempo);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: "
+ e);
}
}
} |
Output:
hashcode : -691830052
Example 2:
// Java program to demonstrate // hashCode() method import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.of( 2003 , 06 , 13 );
// getting hash code of the date
// by using hashCode() method
long tempo = hidate.hashCode();
// display the result
System.out.println( "hashcode : "
+ tempo);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: "
+ e);
}
}
} |
Output:
hashcode : -691914148
