Java MonthDay adjustInto()用法及代码示例

MonthDay类的adjustInto()方法用于将传递的时间对象调整为具有应用此方法的MonthYear。此实例是不可变的，不受此方法调用的影响。

用法:

public Temporal adjustInto(Temporal temporal)

参数：该方法接受时间作为参数，该时间是要调整的目标时间对象。它不能为空。

返回值：此方法返回调整后的对象。

异常：此方法引发以下异常：

DateTimeException–如果无法进行调整。
ArithmeticException–如果无法进行调整。

以下示例程序旨在说明adjustInto()方法：
示例1:

// Java program to demonstrate 
// MonthDay.adjustInto() method 
  
import java.time.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
        // create a MonthDay object 
        MonthDay mday = MonthDay.of(10, 31); 
  
        // print instance 
        System.out.println("MonthDay :"
                           + mday); 
  
        // create a temporal object 
        LocalDate date 
 = LocalDate.parse("2007-12-03"); 
  
        // print instance 
        System.out.println("LocalDate :"
                           + date); 
  
        // apply adjustInto method of Year class 
        LocalDate updatedlocal 
 = (LocalDate)mday.adjustInto(date); 
  
        // print instance 
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal); 
    } 
}

输出：

MonthDay :--10-31
LocalDate :2007-12-03
LocalDate after applying adjustInto method: 2007-10-31

示例2:

// Java program to demonstrate 
// MonthDay.adjustInto() method 
  
import java.time.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
        // create a MonthDay object 
        MonthDay mday = MonthDay.of(12, 22); 
  
        // print instance 
        System.out.println("MonthDay :"
                           + mday); 
  
        // create a temporal object 
        LocalDate date 
 = LocalDate.parse("2017-12-03"); 
  
        // print instance 
        System.out.println("LocalDate :"
                           + date); 
  
        // apply adjustInto method of Year class 
        LocalDate updatedlocal  
= (LocalDate)mday.adjustInto(date); 
  
        // print instance 
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal); 
    } 
}

输出：

MonthDay :--12-22
LocalDate :2017-12-03
LocalDate after applying adjustInto method: 2017-12-22
