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
