Date in Java

Back to: Java Tutorials

In Java, the java.util.Date class represents a date and time value, which can be used to store and manipulate dates and times. The Date class stores the number of milliseconds that have elapsed since January 1, 1970, 00:00:00 UTC (also known as the Unix epoch).

To create a Date object, you can use one of the following constructors:

1. Date(): Creates a Date object representing the current date and time.
2. Date(long millis): Creates a Date object representing the specified number of milliseconds since the Unix epoch.

Once you have a Date object, you can use various methods to manipulate and format the date and time values. For example, you can use the getTime() method to get the number of milliseconds since the Unix epoch, or the toString() method to get a string representation of the date and time value. However, the Date class is considered to be somewhat outdated, and it’s recommended to use the newer java.time package introduced in Java 8, which provides more robust and intuitive date and time handling.
