Java 标准工具类（时间）

Java Date时间转化为字符串

Date date = new Date();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
 simpleDateFormat.format(date);

java lang3 时间格式转化

Date date = new Date();
DateFormatUtils.format(date, "yyyy-MM-dd hh:mm:ss");

java 获取随机时间 faker

Faker faker = new Faker(Locale.CHINA);
Date startTime = DateUtils.addDays(new Date(), -5);
Date endTime = DateUtils.addDays(new Date(), 5);
Date between = faker.date().between(startTime, endTime);

java 增加时间日期 lang3

Date dataAdd = DateUtils.addDays(new Date(), 5);

java 多格式日期匹配

String str = "2023-08-02 09:18:25";
Date date1 = DateUtils.parseDate(str, "yyyy-mm-dd", "yyyy-MM-dd hh:mm:ss");

Java LocalDateTime

LocalDateTime now = LocalDateTime.now();
LocalDateTime start2 = LocalDateTime.of(1995, 1, 1, 20, 25, 1);

比较两个时间之间的差距 LocalDateTime

LocalDateTime start2 = LocalDateTime.of(1995, 1, 1, 20, 25, 1);
LocalDateTime end2 = LocalDateTime.of(1996, 1, 1, 13, 34, 1);
long seconds = Duration.between(start2, end2).getSeconds();
