Interpretation of the technical principles of the MaduraDateTime framework in the Java class library

MaduradateTime is a Java class library for processing date and time.It is based on the Java.time library provided by Joda-Time library and Java 8, and provides more convenient and flexible date-time operation methods. MaduradateTime's technical principles mainly include the following aspects: 1. Internal data structure: MaduradateTime uses an enumeration class called "Chronounit" to indicate different units of the date and time, such as year, month, day, hour, minute, etc.It also uses an interface called "Datetimefield" to represent the date time field, such as year, month, number of days, etc.These data structures can be used to calculate the differences between the date and time and the implementation of addition and subtraction operations. 2. Timeline: MaduradateTime uses a class called "TimeScale" to represent the timeline, which defines the relationship between the date and time.The timeline is calculated based on different calendar (such as Giri calendar, Confucian calendar, etc.), and can be switched as needed. 3. Time zone processing: MaduradateTime provides rich time zone processing functions, which can handle conversion and calculations between different time zones.It uses Java 8's java.time.zone package to obtain time zone information and uses the time zone offset for related calculations. 4. Date time calculation: MaduradateTime provides a series of convenient date and time calculation methods.For example, you can use the DateTimeField interface to implement the addition and subtraction of the date field. You can use the Chronounit enumeration class to achieve the addition and subtraction operation of the date time unit.It can also perform operations, formatting, analysis and other operations of date and time. The following is a simple MaduradateTime example code: import nz.net.ultraq.thymeleaf.expression.MaduraDateTime; public class MaduraDateTimeExample { public static void main(String[] args) { MaduraDateTime maduraDateTime = new MaduraDateTime(); // Get the current date time System.out.println ("Current Date Time:" + Maduradatetime.now ()); // Get the current date System.out.println ("current date:" + Maduradatetime.today ()); // Get the current time System.out.println ("current time:" + Maduradatetime.nowtime ()); // Add subtraction days System.out.println ("Plus 10 days later:" + Maduradatetime.adddDDDAys (10)); // Calculate the gap between the number of days between the two dates System.out.println ("The number of days between two dates:" + Maduradatetime.diffdays ("2022-01-01", "2022-02-01"););););););););) // Formatting date time System.out.println ("Formatting Date:" + Maduradatetime.Format ("2022-01-01", "Yyyy Year MM Month DD Day")););); // Analyze the date string as MaduradateTime object String dateStr = "2022-01-01"; MaduraDateTime parsedDateTime = maduraDateTime.parse(dateStr); System.out.println ("The date object after analysis:" + ParsedDatetime); } } The above code shows some of the basic usage of the MaduraDateTime class library, including the operations such as obtaining the current date time, date time, date calculation, formatting, and analysis.By using MaduradateTime, we can easily handle the operating needs of the date and time.
