What Is Class Data Structure?

The Class Data Structure is a fundamental concept in programming that allows us to create our own custom data types. It is a blueprint or template that defines the properties and behaviors of an object. In this article, we will explore what a class is, how it is defined, and how we can use it to create objects.

Defining a Class

To define a class in HTML, we use the <class> element. Inside the <class> element, we can define various properties and methods that will be associated with objects created from this class.

Syntax:

We start by using the <class> tag followed by the name of the class. Inside the opening and closing tags of the <class> element, we define the properties and methods of our class using appropriate HTML elements.

For example, let’s create a simple class called “Person” with two properties: “name” and “age”.

<class>
  <p><b>Person</b></p>
  <p><b>Properties:</b></p>
  <ul>
    <li>name</li>
    <li>age</li>
  </ul>
  <p><b>Methods:</b></p>
  <p/>
</class>

Creating Objects

Once we have defined our class, we can create objects from it. An object is an instance of a class and has access to all the properties and methods defined in the class.

To create an object in HTML, we use the <object> element. Inside the opening and closing tags of the <object> element, we specify the class name using the class attribute.

For example, let’s create two objects of the “Person” class:

<object class="Person"></object>
<object class="Person"></object>

Accessing Properties and Methods

To access properties and methods of an object, we can use various HTML elements. For example, to access a property, we can use the <p> element with appropriate styling elements like or .

<p><b>Object 1:</b></p>
<p><b>Name:</b> John Doe</p>
<p><b>Age:</b> 25</p>

<p/>

<p><b>Object 2:</b></p>
<p style="text-decoration: underline;"><b style="text-decoration: none;">Name:</b style="text-decoration: none;"> Jane Smith</p style="text-decoration: underline;">
<p style="text-decoration: underline;"><b style="text-decoration: none;">Age:</b style="text-decoration: none;"> 30</p style="text-decoration: underline;">
