Java 中的 ChronoPeriod hashCode()方法，示例
原文:https://www . geesforgeks . org/chronoperiod-hashcode-method-in-Java-with-examples/
Java 中计时周期类的 hashCode()方法用来获取这个周期生成的 hashCode。
语法:
int hashCode()
参数:该方法不接受任何参数。
返回值:该方法返回给定期间生成的 hashCode。
下面的程序说明了 Java 中的 hashCode()方法:
程序 1 :
// Java code to show the function hashCode()
// to get the hashCode for the given period
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to generate hashCode for the given period
static void getNumberOfDays(int year, int months, int days)
{
ChronoPeriod period = Period.of(year, months, days);
System.out.println(period.hashCode());
}
// Driver Code
public static void main(String[] args)
{
int year = 12;
int months = 3;
int days = 31;
getNumberOfDays(year, months, days);
}
}
输出:
2032396
程序二 :
// Java code to show the function hashCode()
// to get the hashCode for the given period
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to generate hashCode for the given period
static void getNumberOfDays(int year, int months, int days)
{
ChronoPeriod period = Period.of(year, months, days);
System.out.println(period.hashCode());
}
// Driver Code
public static void main(String[] args)
{
int year = -12;
int months = 3;
int days = 31;
getNumberOfDays(year, months, days);
}
}
输出:
2032372
