Java中的 ChronoPeriod hashCode() 方法及示例
Java中ChronoPeriod 类的hashCode() 方法用于获取该周期生成的 hashCode。
句法:
int hashCode()
参数:此方法不接受任何参数。
返回值:此方法返回为给定时间段生成的 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
方案二:
// 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
