上述程序请修改为计算可用工作时段时 包含非工作时间也算作连续的工作时段

以下是修改后的代码实现：

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;

public class DeviceScheduleChecker {
    
    public static void main(String[] args) {
        String dailyWorkingTime = "08:00-09:00;13:00-15:00";
        String availableWorkingTime = "08:58-09:00;13:00-14:00";
        int requiredWorkingTime = 50;
        boolean canPerform = checkDeviceSchedule(dailyWorkingTime, availableWorkingTime, requiredWorkingTime);
        System.out.println(canPerform);
    }
    
    public static boolean checkDeviceSchedule(String dailyWorkingTime, String availableWorkingTime, int requiredWorkingTime) {
        List<TimeSlot> dailySchedule = parseTimeSlots(dailyWorkingTime);
        List<TimeSlot> availableSlots = parseTimeSlots(availableWorkingTime);
        for (TimeSlot availableSlot : availableSlots) {
            int availableTime = availableSlot.getDuration();
            for (TimeSlot dailySlot : dailySchedule) {
                if (dailySlot.overlapsWith(availableSlot)) {
                    int overlapDuration = dailySlot.getOverlapDuration(availableSlot);
                    availableTime += overlapDuration;
                }
            }
            if (availableTime >= requiredWorkingTime) {
                return true;
            }
        }
        return false;
    }
    
    private static List<TimeSlot> parseTimeSlots(String timeString) {
        List<TimeSlot> timeSlots = new ArrayList<>();
        String[] timeRanges = timeString.split(";");
        for (String timeRange : timeRanges) {
            String[] parts = timeRange.split("-");
            TimeSlot slot = new TimeSlot(parts[0], parts[1]);
            timeSlots.add(slot);
        }
        return timeSlots;
    }
    
    private static class TimeSlot {
        private Date startTime;
        private Date endTime;
        
        public TimeSlot(String start, String end) {
            DateFormat format = new SimpleDateFormat("HH:mm");
            try {
                this.startTime = format.parse(start);
                this.endTime = format.parse(end);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
        
        public boolean overlapsWith(TimeSlot other) {
            return this.startTime.before(other.endTime) && this.endTime.after(other.startTime);
        }
        
        public int getOverlapDuration(TimeSlot other) {
            Date overlapStart = this.startTime.before(other.startTime) ? other.startTime : this.startTime;
            Date overlapEnd = this.endTime.after(other.endTime) ? other.endTime : this.endTime;
            long overlapDuration = overlapEnd.getTime() - overlapStart.getTime();
            return (int) (overlapDuration / (1000 * 60));
        }
        
        public int getDuration() {
            long duration = this.endTime.getTime() - this.startTime.getTime();
            return (int) (duration / (1000 * 60));
        }
    }
}

这个代码解析了两个时间段字符串，将它们转换为 `TimeSlot` 对象的列表。然后，对于每个剩余的可用工作时间段，它计算了该时间段与日常工作时间段的重叠时间，并将该重叠时间添加到此时间段的可用工作时间内。最后，它检查是否有任何可用工作时间段满足所需的工作时间，如果有，则返回true，否则返回false。在这个版本中，如果可用工作时间段包含了非工作时间，则仍然将其视为连续的工作时段。
