JAVA 1.传入设备的日常工作时间段（HH:mm-HH:mm;HH:mm-HH:mm;HH:mm-HH:mm） 1.传入某工序需要的工作时间（分） 2.传入这个设备空闲时间段如（HH:mm-HH:mm;HH:mm-HH:mm;HH:mm-HH:mm;HH:mm-HH:mm) 3.判断这个设备空闲时间段时间是否满足工序的工作时间需要 返回true或false 注意:设备满足工序的时间段必须是除休息时间段外的连续工作时间段

好的，让我来帮您解答这个问题。您可以按照以下步骤实现：

1. 将传入的设备日常工作时间段和空闲时间段拆分成多个时间段，并分别存储为列表，每个时间段包含开始时间和结束时间。
2. 遍历设备空闲时间段列表，对于每个时间段，判断是否有足够的时间来完成所需工作。如果有，则返回true，否则继续遍历。
3. 在判断时间段是否足够完成工作时，需要注意排除休息时间段。可以将休息时间段从设备日常工作时间段中去除，然后再进行计算。

以下是示例代码，供您参考：

import java.util.ArrayList;
import java.util.List;

public class Device {
    private List<TimePeriod> dailyWorkTime = new ArrayList<>();
    private int workTimeNeeded;
    private List<TimePeriod> freeTime = new ArrayList<>();

    public Device(String dailyWorkTimeStr, int workTimeNeeded, String freeTimeStr) {
        // 解析传入的时间段字符串，构造时间段列表
        this.dailyWorkTime = parseTimePeriodList(dailyWorkTimeStr);
        this.workTimeNeeded = workTimeNeeded;
        this.freeTime = parseTimePeriodList(freeTimeStr);
    }

    public boolean canWork() {
        // 去除休息时间段
        List<TimePeriod> workTime = new ArrayList<>(dailyWorkTime);
        for (TimePeriod free : freeTime) {
            workTime = subtractTimePeriod(workTime, free);
        }

        // 遍历设备空闲时间段，判断是否有足够的时间完成工作
        for (TimePeriod free : freeTime) {
            List<TimePeriod> availableTime = intersectTimePeriod(workTime, free);
            for (TimePeriod period : availableTime) {
                if (period.duration() >= workTimeNeeded) {
                    return true;
                }
            }
        }

        return false;
    }

    // 解析时间段列表
    private List<TimePeriod> parseTimePeriodList(String timeStr) {
        List<TimePeriod> list = new ArrayList<>();
        String[] parts = timeStr.split(";");
        for (String part : parts) {
            String[] times = part.split("-");
            list.add(new TimePeriod(times[0], times[1]));
        }
        return list;
    }

    // 计算时间段交集
    private List<TimePeriod> intersectTimePeriod(List<TimePeriod> list1, TimePeriod period) {
        List<TimePeriod> result = new ArrayList<>();
        for (TimePeriod p : list1) {
            TimePeriod intersect = p.intersect(period);
            if (intersect != null) {
                result.add(intersect);
            }
        }
        return result;
    }

    // 计算时间段差集
    private List<TimePeriod> subtractTimePeriod(List<TimePeriod> list1, TimePeriod period) {
        List<TimePeriod> result = new ArrayList<>();
        for (TimePeriod p : list1) {
            List<TimePeriod> subtract = p.subtract(period);
            result.addAll(subtract);
        }
        return result;
    }
}

class TimePeriod {
    private int startHour;
    private int startMinute;
    private int endHour;
    private int endMinute;

    public TimePeriod(String start, String end) {
        String[] startParts = start.split(":");
        this.startHour = Integer.parseInt(startParts[0]);
        this.startMinute = Integer.parseInt(startParts[1]);

        String[] endParts = end.split(":");
        this.endHour = Integer.parseInt(endParts[0]);
        this.endMinute = Integer.parseInt(endParts[1]);
    }

    public int duration() {
        return (endHour - startHour) * 60 + (endMinute - startMinute);
    }

    public TimePeriod intersect(TimePeriod other) {
        int startHour = Math.max(this.startHour, other.startHour);
        int startMinute = Math.max(this.startMinute, other.startMinute);
        int endHour = Math.min(this.endHour, other.endHour);
        int endMinute = Math.min(this.endMinute, other.endMinute);

        if (startHour < endHour || (startHour == endHour && startMinute < endMinute)) {
            return new TimePeriod(String.format("%02d:%02d", startHour, startMinute),
                    String.format("%02d:%02d", endHour, endMinute));
        } else {
            return null;
        }
    }

    public List<TimePeriod> subtract(TimePeriod other) {
        List<TimePeriod> result = new ArrayList<>();

        if (this.startHour < other.startHour) {
            result.add(new TimePeriod(String.format("%02d:%02d", this.startHour, this.startMinute),
                    String.format("%02d:%02d", other.startHour, other.startMinute)));
        }

        if (this.endHour > other.endHour) {
            result.add(new TimePeriod(String.format("%02d:%02d", other.endHour, other.endMinute),
                    String.format("%02d:%02d", this.endHour, this.endMinute)));
        }

        return result;
    }
}

您可以通过以下方式测试代码：

public static void main(String[] args) {
    Device device = new Device("08:00-12:00;13:00-17:00", 120, "09:00-11:00;13:30-15:30");
    System.out.println(device.canWork()); // true

    Device device2 = new Device("08:00-12:00;13:00-17:00", 120, "16:00-18:00");
    System.out.println(device2.canWork()); // false
}

希望能帮助到您！
