Java:如何检查Date是否在一定范围内？

import java.util.Date;

public class DateRangeChecker {
    public static void main(String[] args) {
        // 创建Date对象
        Date dateToCheck = new Date();

        // 设置范围的起始和结束时间
        Date startDate = new Date(1637251200000L); // 2021-11-25 00:00:00
        Date endDate = new Date(1637856000000L); // 2021-12-01 00:00:00

        // 检查Date是否在范围内
        boolean isInRange = isDateInRange(dateToCheck, startDate, endDate);

        if (isInRange) {
            System.out.println("Date is in range.");
        } else {
            System.out.println("Date is not in range.");
        }
    }

    public static boolean isDateInRange(Date dateToCheck, Date startDate, Date endDate) {
        // 将Date对象转换为时间戳
        long dateToCheckTimestamp = dateToCheck.getTime();
        long startDateTimestamp = startDate.getTime();
        long endDateTimestamp = endDate.getTime();

        // 比较时间戳
        return (dateToCheckTimestamp >= startDateTimestamp) && (dateToCheckTimestamp <= endDateTimestamp);
    }
}
