Time conversion tool class (behind the sample code), copy and use
1. API example:
1.1 Calculate the time difference based on the two incoming localDateTime and convert it to the corresponding days, hours, minutes, and seconds
LocalDateTime start = LocalDateTime.of(2022, 2, 21, 7, 20, 30);
LocalDateTime end = LocalDateTime.of(2022, 2, 22, 8, 30, 50);
String date = GetDateUtils.getDate(start, end);
System.out.println(date); // 输出 1天1时10分20秒1.2 Calculate the time difference based on the two incoming localDateTime and convert it to the corresponding hour, minute, and second in the format of 00:00:00
LocalDateTime start = LocalDateTime.of(2022, 2, 21, 7, 20, 30);
LocalDateTime end = LocalDateTime.of(2022, 2, 22, 8, 30, 50);
String date = GetDateUtils.getHMS(start, end);
System.out.println(date); // 输出 25:10:20 即相差25时10分钟20秒1.3 Calculate the time difference based on the two incoming localDateTimes and convert them to minutes and seconds in the corresponding 00:00 format
LocalDateTime start = LocalDateTime.of(2022, 2, 21, 7, 20, 30);
LocalDateTime end = LocalDateTime.of(2022, 2, 22, 8, 30, 50);
String date = GetDateUtils.getMinSecond(start, end);
System.out.println(date); // 输出 1510:20 即相差1510分钟20秒1.4 Convert to seconds according to the incoming time, minutes and seconds (minutes and seconds) format 00:00:00 (00:00)
LocalDateTime start = LocalDateTime.of(2022, 2, 21, 7, 20, 30);
LocalDateTime end = LocalDateTime.of(2022, 2, 22, 8, 30, 50);
String date = GetDateUtils.getHMS(start, end);
System.out.println(date); // 输出 25:10:20
Long second = GetDateUtils.getSecond(date);
System.out.println("相差秒数：" + second);
