Java 中带(临时调整)方法的计时本地日期，示例

原文:https://www . geeksforgeeks . org/chronolocaldata-with temporalaadjuster-method-in-Java-with-examples/

用计时定位日期界面的方法，使用作为参数传递的时间调整值调整该日期时间，调整后返回调整后的日期时间的副本。使用指定的调整器策略对象进行调整。ChronoLocalDate 的这个实例是不可变的，不受这个方法调用的影响。

语法:

public ChronoLocalDate with(TemporalAdjuster adjuster)

参数:该方法接受调节器作为参数，调节器使用该参数。

返回值:该方法基于此返回一个进行了调整的 ChronoLocalDate。

异常:此方法抛出以下异常:

  • Abnormal date and time -If it cannot be adjusted.
  • Arithmetic exception -If there is a numerical overflow.

下面的程序说明了 with()方法:

程序 1:

// Java program to demonstrate
// ChronoLocalDate.with() method

import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;

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

        // create a LocalDate object
        ChronoLocalDate local
            = LocalDate.parse(
                "2018-12-06");

        // print instance
        System.out.println("ChronoLocalDate before"
                           + " adjustment: "
                           + local);

        // apply with method of LocalDate class
        ChronoLocalDate updatedlocal
            = local.with(Month.MARCH)
                  .with(TemporalAdjusters
                            .lastDayOfMonth());

        // print instance
        System.out.println("ChronoLocalDate after"
                           + " adjustment: "
                           + updatedlocal);
    }
}

输出:

ChronoLocalDate before adjustment: 2018-12-06
ChronoLocalDate after adjustment: 2018-03-31
