Java 中的 Year adjustInto()方法，带示例

原文:https://www . geesforgeks . org/year-adjustin to-method-in-Java-with-examples/

adjustInto() 方法的 Year 类用于调整传递的时态对象，使其具有应用该方法的年份。此实例是不可变的，不受此方法调用的影响。

语法:

public Temporal adjustInto(Temporal temporal)

参数:该方法接受时间作为参数，该参数是要调整的目标时间对象。它不应为空。

返回值:此方法返回调整后的对象。

异常:该方法抛出以下异常:

  • 日期时间异常–如果无法进行调整。
  • 算术异常–如果出现数值溢出。

以下程序说明了 adjustInto()方法: 程序 1:

// Java program to demonstrate
// Year.adjustInto() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a Year object
        Year yr
            = Year.of(2019);

        // 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)yr.adjustInto(date);

        // print instance
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal);
    }
}

Output:

LocalDate :2007-12-03
LocalDate after applying adjustInto method: 2019-12-03

程序 2:

// Java program to demonstrate
// Year.adjustInto() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {
        // create a Year object
        Year yr
            = Year.of(2032);

        // create a temporal object
        LocalDate date = LocalDate.parse("2017-01-13");

        // print instance
        System.out.println("LocalDate :"
                           + date);

        // apply adjustInto method of Year class
        LocalDate updatedlocal = (LocalDate)yr.adjustInto(date);

        // print instance
        System.out.println("LocalDate after"
                           + " applying adjustInto method: "
                           + updatedlocal);
    }
}

Output:

LocalDate :2017-01-13
LocalDate after applying adjustInto method: 2032-01-13
