该文章介绍了一个Java类`WorkDaysCalculator`，用于计算两个指定日期之间的工作日，排除法定假日并考虑包含特殊工作日的情况。

import java.time.DayOfWeek;
import java.time.LocalDate;
import java.util.ArrayList;
import java.util.List;
/**
 * 获取两个日期之间的工作日
 */
public class WorkDaysCalculator {

  public static int calculateWorkDays(LocalDate startDate, LocalDate endDate,
      List<LocalDate> excludedDates,List<LocalDate> containsDates) {
    int workDays = 0;
    LocalDate date = startDate;
    while (!date.isAfter(endDate)) {
      if (isWorkDay(excludedDates, date) || containsDates.contains(date)) {
        workDays++;
        System.out.println(date);
      }
      date = date.plusDays(1);
    }
    return workDays;
  }

  private static boolean isWorkDay(List<LocalDate> excludedDates, LocalDate date) {
    return date.getDayOfWeek() != DayOfWeek.SATURDAY &&
        date.getDayOfWeek() != DayOfWeek.SUNDAY &&
        !excludedDates.contains(date);
  }

  public static void workDays(){
    try {
      //开始天
      LocalDate startDate = LocalDate.of(2024, 2, 1);
      //结束天
      LocalDate endDate = LocalDate.of(2024, 3, 8);
      //排除周六日之外的法定休息日
      List<LocalDate> excludedDates = new ArrayList<>();
      excludedDates.add(LocalDate.of(2024, 2, 12));
      excludedDates.add(LocalDate.of(2024, 2, 13));
      excludedDates.add(LocalDate.of(2024, 2, 14));
      excludedDates.add(LocalDate.of(2024, 2, 15));
      excludedDates.add(LocalDate.of(2024, 2, 16));

      //加上是周六日的工作日
      List<LocalDate> containsDates = new ArrayList<>();
      containsDates.add(LocalDate.of(2024, 2, 4));
      containsDates.add(LocalDate.of(2024, 2, 18));


      int workDays = calculateWorkDays(startDate, endDate, excludedDates, containsDates);
      System.out.println();
      System.out.println( "从"+startDate + " 到 " + endDate + "的工作日有: " + workDays+"天");

    }catch (Exception e){
      System.out.println("无效日期！！！");
    }
  }

  public static void main(String[] args) {
     workDays();
  }
}
