如何检查数组是否在Java中包含三个连续的日期？
要检查以确定给定数组是否包含三个连续的日期，请执行以下操作：
将给定的数组转换为LocalDate类型的列表。
如果该列表包含3个连续元素，则使用LocalDate类的方法比较列表的ith，i+1和i+1，i+2个元素。
示例
import java.time.LocalDate;
import java.time.Month;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Date;
import java.util.List;
public class ConsicutiveDate {
public static void main(String args[]) {
String[] dates = {"5/12/2017", "6/12/2017", "7/12/2017"};
List<LocalDate> localDateList = new ArrayList<>();
for (int i = 0; i<dates.length; i++) {
String[] data = dates[i].split("/");
Month m = Month.of(Integer.parseInt(data[1]));
LocalDate localDate =
LocalDate.of(Integer.parseInt(data[2]),m,Integer.parseInt(data[0]));
localDateList.add(localDate);
Date date = java.sql.Date.valueOf(localDate);
}
System.out.println("Contents of the list are ::"+localDateList);
Collections.sort(localDateList);
for (int i = 0; i < localDateList.size() - 1; i++) {
LocalDate date1 = localDateList.get(i);
LocalDate date2 = localDateList.get(i + 1);
if (date1.plusDays(1).equals(date2)) {
System.out.println("Consecutive Dates are: " + date1 + " and " + date2);
}
}
}
}输出结果
Contents of the list are ::[2017-12-05, 2017-12-06, 2017-12-07] Consecutive Dates are: 2017-12-05 and 2017-12-06 Consecutive Dates are: 2017-12-06 and 2017-12-07
