5. What is polymorphism in Java and how is it implemented?
Polymorphism allows objects to be treated as instances of their parent class rather than their actual class. It can be implemented in two ways:
- Compile-time polymorphism: Achieved through method overloading.
- Runtime polymorphism: Achieved through method overriding.
6. How does exception handling work in Java?
Exception handling in Java is managed using try, catch, finally, and throw/throws. The try block contains code that might throw an exception, catch block handles the exception, finally block executes code regardless of whether an exception occurs, and throw/throws is used to throw exceptions.
7. What is the difference between ArrayList and LinkedList in Java?
- ArrayList: Implements the List interface using a dynamic array. It offers constant-time positional access but is slow for inserting or deleting elements from the middle.
- LinkedList: Implements the List and Deque interfaces using a doubly-linked list. It offers faster insertions and deletions but slower positional access compared to ArrayList.
8. Explain the concept of multithreading in Java.
Multithreading is a process of executing multiple threads simultaneously to maximize CPU utilization. Threads are lightweight sub-processes, and Java provides built-in support for multithreading through the java.lang.Thread class and the java.util.concurrent package.
9. What is the purpose of the final keyword in Java?
The final keyword is used to define constants, prevent method overriding, and inheritance. When applied to a variable, it makes it a constant. When applied to a method, it prevents subclasses from overriding it. When applied to a class, it prevents the class from being subclassed.
10. What is garbage collection in Java and how does it work?
Garbage collection is an automatic memory management feature in Java that deallocates memory occupied by objects that are no longer in use, preventing memory leaks. The JVM’s garbage collector identifies and removes these objects. Java developers can request garbage collection using System.gc(), but it is not guaranteed to run immediately.

4. How do you create a hyperlink in HTML?
A hyperlink is created using the <a> (anchor) tag with the href attribute specifying the URL of the link. For example:
<a href="https://www.example.com">Visit Example</a>
5. What are HTML forms and how do you create one?
HTML forms are used to collect user input and are created using the <form> tag. Forms contain various input elements like text fields, radio buttons, checkboxes, and submit buttons. For example:
<form action="/submit" method="post">
<input type="text" name="username">
<input type="password" name="password">
<input type="submit" value="Submit">
</form>
6. Explain the difference between the <div> and <span> tags.
The <div> tag is a block-level element used to group larger sections of content, creating distinct blocks. The <span> tag is an inline element used to group small portions of text or other inline elements. <div> typically affects the layout by creating line breaks, while <span> does not.
7. What is the purpose of the <meta> tag in HTML?
The <meta> tag provides metadata about the HTML document, such as character encoding, viewport settings for responsive design, and SEO-related information like descriptions and keywords. Meta tags are placed within the <head> section of the HTML document.
8. How do you include an image in an HTML page?
An image is included using the <img> tag with the src attribute specifying the path to the image file and the alt attribute providing alternative text for accessibility. For example:
<img src="image.jpg" alt="Description of image">
9. What is the difference between inline, inline-block, and block elements in HTML?
- Inline elements (e.g., <span>, <a>) do not start on a new line and only take up as much width as necessary.
- Block elements (e.g., <div>, <p>) start on a new line and take up the full width available.
- Inline-block elements (e.g., <img>) are similar to inline elements but allow setting width and height, behaving like a combination of inline and block elements.
10. How do you embed a video in an HTML page?
A video is embedded using the <video> tag with the src attribute specifying the video file. You can include optional attributes like controls for playback controls and autoplay to start playing the video automatically. For example:
<video src="video.mp4" controls>
Your browser does not support the video tag.
</video>
