In this article, you'll learn several ways of comparing Dates, Times, DateTimes, and DateTimes in different TimeZones in Java. We use the DateTime API introduced in Java 8 like LocalDate, LocalTime, LocalDateTime, ZonedDateTime, as well as older classes like Date, and Calendar to demonstrate how to compare dates Converting a string to a date in Java (or any programming language) is a fundamental skill and is useful to know when working on projects. Sometimes, it's simply easier to work with a string to represent a date, and then convert it into a Date object for further use. In this article, we'll go over the many methods and libraries you can use to convert a Java string into a date object For example, the existing classes (such as java.util.Date and SimpleDateFormatter) aren't thread-safe, leading to potential concurrency issues for users—not something the average developer would expect to deal with when writing date-handling code.. Some of the date and time classes also exhibit quite poor API design. For example, years in java.util.Date start at 1900, months start at 1. Java LocalDateTime class is an immutable date-time object that represents a date-time, with the default format as yyyy-MM-dd-HH-mm-ss.zzz.
