Java中的 TemporalAdjusters lastDayOfYear() 方法及示例

TemporalAdjusters 类的lastDayOfYear()方法用于返回“一年中的最后一天” TemporalAdjuster 对象，该对象返回设置为一年中最后一天的新 Date 对象。

句法：

public static TemporalAdjuster lastDayOfYear()

参数：此方法不接受任何内容。

返回值：该方法返回年份调整器的最后一天，不为空。

下面的程序说明了 TemporalAdjusters.lastDayOfYear() 方法：
方案一：

// Java program to demonstrate
// TemporalAdjusters.lastDayOfYear()
  
import java.time.LocalDate;
import java.time.temporal.TemporalAdjuster;
import java.time.temporal.TemporalAdjusters;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // get TemporalAdjuster with last day
        // of the year adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.lastDayOfYear();
  
        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(2023, 10, 11);
        LocalDate lastDayOfYear
            = localDate.with(temporalAdjuster);
  
        // print
        System.out.println("last day of the "
                           + "year for localdate "
                           + localDate + ": "
                           + lastDayOfYear);
    }
}

输出：

last day of the year for localdate 2023-10-11: 2023-12-31

方案二：

// Java program to demonstrate
// TemporalAdjusters.lastDayOfYear() method
  
import java.time.LocalDate;
import java.time.temporal.TemporalAdjuster;
import java.time.temporal.TemporalAdjusters;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // get TemporalAdjuster with last day
        // of  year adjuster
        TemporalAdjuster temporalAdjuster
            = TemporalAdjusters.lastDayOfYear();
  
        // using adjuster for local date time
        LocalDate localDate
            = LocalDate.of(2099, 12, 29);
        LocalDate lastDayOfYear
            = localDate.with(temporalAdjuster);
  
        // print
        System.out.println("last day of  "
                           + "year for localdate "
                           + localDate + ": "
                           + lastDayOfYear);
    }
}

输出：

last day of  year for localdate 2099-12-29: 2099-12-31
