Java method to determine whether a time is today

java determines whether the time is today:

public class Test {
    /**
     * java 判断一个时间是不是今天的时间范围内
     * @param args
     */
    public static void main(String[] args) {
        String time = "2017-09-27 11:20:45";
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm:ss");
        LocalDateTime localTime = LocalDateTime.parse(time, dtf);
        LocalDateTime startTime = LocalDate.now().atTime(0, 0, 0);
        LocalDateTime endTime = LocalDate.now().atTime(23, 59, 59);
        //如果小于今天的开始日期
        if (localTime.isBefore(startTime)) {
            System.out.println("时间是过去");
        }
        //如果大于今天的开始日期，小于今天的结束日期
        if (localTime.isAfter(startTime) && localTime.isBefore(endTime)) {
            System.out.println("时间是今天");
        }
        //如果大于今天的结束日期
        if (localTime.isAfter(endTime)) {
            System.out.println("时间是未来");
        }
    }
}

java.time.LocalTime.isAfter(LocalTime other) method checks whether this time is after the specified time.
