带有示例的Java中的 HijrahDate hashCode() 方法
Java.time.chrono.HijrahDate类的hashCode()方法用于获取特定回历日期的哈希码。
句法:
public int hashCode()
参数:此方法不接受任何参数作为参数。
返回值:此方法返回特定回历日期的哈希码。
以下是说明hashCode()方法的示例:
示例 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
// HijrahDate Object
HijrahDate hidate = HijrahDate.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);
}
}
}
输出:
hashcode : 2097279521
示例 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
// HijrahDate Object
HijrahDate hidate
= HijrahDate.of(1345, 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);
}
}
}
输出:
hashcode : 2097607230
