Java中的 IsoChronology getId() 方法与示例

Java.time.chrono.IsoChronology 类getId()方法用于检索撤销 getId() 方法的特定年表的标识状态。

句法:

public String getId()

参数:此方法不接受任何参数作为参数。

返回值:此方法返回 getId() 方法被撤销的特定年表的标识状态。

以下是说明getId()方法的示例:

示例 1:

// Java program to demonstrate
// getId() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // LocalDate Object
        LocalDate hidate = LocalDate.now();
  
        // getting IsoChronology
        // used in LocalDate
        IsoChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using getId() method
        String id = crono.getId();
  
        // display the result
        System.out.println("id : " + id);
    }
}
输出:
id : ISO

示例 2:

// Java program to demonstrate
// getId() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing
        // LocalDate Object
        LocalDate hidate = LocalDate.now(Clock.systemDefaultZone());
  
        // getting IsoChronology
        // used in LocalDate
        IsoChronology crono
            = hidate.getChronology();
  
        // getting id of this Chronology
        // by using getId() method
        String id = crono.getId();
  
        // display the result
        System.out.println("id : " + id);
    }
}
输出:
id : ISO
