Java Period hashCode()用法及代码示例


Java中Period类的hashCode()方法用于获取此期间生成的hashCode。

用法:

public int hashCode()

参数:此方法不接受任何参数。


返回值:此方法返回在给定时间段内生成的hashCode。

以下程序说明了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.Period; 
import java.time.temporal.ChronoUnit; 
  
public class PeriodDemo { 
  
    // Function to generate hashCode for the given period 
    static void getNumberOfDays(int year, int months, int days) 
    { 
        Period 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2

// Java code to show the function hashCode() 
// to get the hashCode for the given period 
  
import java.time.Period; 
import java.time.temporal.ChronoUnit; 
  
public class PeriodDemo { 
  
    // Function to generate hashCode for the given period 
    static void getNumberOfDays(int year, int months, int days) 
    { 
        Period 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
