如何验证Android中小于开始日期的结束日期？

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.time.format.DateTimeParseException;

public class DateValidator {

    public static boolean isEndDateBeforeStartDate(String startDateStr, String endDateStr) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        try {
            LocalDate startDate = LocalDate.parse(startDateStr, formatter);
            LocalDate endDate = LocalDate.parse(endDateStr, formatter);
            return endDate.isBefore(startDate);
        } catch (DateTimeParseException e) {
            // 日期格式不正确
            return false;
        }
    }

    public static void main(String[] args) {
        String startDate = "2023-10-01";
        String endDate = "2023-09-30";

        if (isEndDateBeforeStartDate(startDate, endDate)) {
            System.out.println("结束日期早于开始日期");
        } else {
            System.out.println("结束日期不早于开始日期");
        }
    }
}
