Java HijrahDate hashCode()用法及代碼示例

java.time.chrono.HijrahDate類的hashCode()方法用於獲取特定hijrah日期的哈希碼。

用法:

public int hashCode()

參數：此方法不接受任何參數作為參數。

返回值：此方法返回特定回曆日期的哈希碼。

下麵是說明hashCode()方法的示例：

範例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); 
        } 
    } 
}

輸出：

hashcode:2097279521

範例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); 
        } 
    } 
}

輸出：

hashcode:2097607230
