Introduction to methods and usage of using Date and SimpleDateFormat classes to process time in Java
Apr 21, 2023 pm 03:01 PM
1. Introduction The Date class in the java.util package represents a specific time, accurate to milliseconds. If we want to use our Date class, then we must introduce our Date class. Writing the year directly into the Date class will not produce the correct result. Because Date in Java is calculated from 1900, so as long as you fill in the first parameter with the number of years since 1900, you will get the year you want. The month needs to be subtracted by 1, and the day can be inserted directly. This method is rarely used, and the second method is commonly used. This method is to convert a string that conforms to a specific format, such as yyyy-MM-dd, into Date type data. First, define an object of Date type Date

How to use Java8 Time API
Apr 28, 2023 pm 12:25 PM
1. Overview As part of this article, let us start with some problems with the existing Date and CalendarAPI and explore how the new Java8Date and TimeAPI solve these problems. We will also take a look at the core classes in the Java8 time class library, such as LocalDate, LocalTime, LocalDateTime, ZonedDateTime, Period, Duration and their APIs. 2. The problem of thread safety of the old time API (before Java 8)-Date and Calendar classes are not thread-safe, making it difficult for developers to debug concurrency problems of these APIs and need to write additional code to deal with them.
