The date tag makes it simple and quick to format a Date. The key 'struts.date.format' in the properties file allows the user to select a custom format (for example, "dd/MM/yyyy hh:mm"), generate easily understandable notations, or just fall back on a predefined format.
<s:date name="dateField" format="dateFormat" />package com.coding.ninjas.struts2.action;
import java.util.Calendar;
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
public class DataTagAction extends ActionSupport
{
private static final long serialVersionUID = -7744420104547018874 L;
private Date birthday;
private Calendar calendar = Calendar.getInstance();
public String execute()
{
calendar.set(1983, 7, 6);
birthday = calendar.getTime();
return SUCCESS;
}
public Date getBirthday()
{
return birthday;
}
public void setBirthday(Date birthday)
{
this.birthday = birthday;
}
}
Create a file with the name success.jsp and put the below content into it.

To produce a War file:
Structs is an open-source Java framework used for developing JAVA EE web applications. Many developers use it as it allows them to build maintainable, flexible, and extensible web applications faster.
A data structure called a set is used in Java to contain distinct components. There can be no duplicates in a set collection. The equals() and hashCode() methods must be implemented for an element to be added to a set.
An object-relational mapping (ORM) tool makes it easier to create, manipulate, and store objects and makes them more accessible. It offers a means of translating programming languages (such as Python and Java) into objects that can be mapped to a SQL database.
The struts.xml file contains the configuration information that will modify as actions are generated. For an application using this file, such as struts, DevMode = false, and other default choices provided in property files can be modified.
The action tag allows programmers to execute the action specified on the view page. They can do this by giving the activity a name. They can set the "executeResult" option to "true" to render the result directly in the view.
In this article, we learned the structs 2 date tag concept. We have also discussed the concept of the date tag using an example.
I hope you would have gained a better understanding of these topics now!
