- Q1. How does ajax call work
- Ans.
Ajax calls allow for asynchronous communication between client and server without reloading the page.
Ajax stands for Asynchronous JavaScript and XML
Uses XMLHttpRequest object to send and receive data
Allows for partial page updates without reloading the entire page
Can handle data in various formats such as JSON, XML, HTML, and plain text
Example: $.ajax({url: 'example.com', success: function(data){console.log(data)}});
- Q2. Difference between REST and SOAP
- Ans.
REST is lightweight and uses HTTP while SOAP is XML-based and has more features.
REST uses HTTP methods like GET, POST, PUT, DELETE while SOAP uses XML messaging.
REST is stateless while SOAP can maintain state.
REST is faster and easier to use while SOAP is more secure and reliable.
REST is used for web services while SOAP is used for enterprise-level services.
Example of REST: Twitter API. Example of SOAP: Amazon Web Serv
- Q3. What is GET and POST
- Ans.
GET and POST are HTTP methods used for sending data to a server.
GET is used to retrieve data from a server
POST is used to submit data to a server
GET requests can be cached and bookmarked
POST requests are not cached and cannot be bookmarked
GET requests have length restrictions
POST requests have no length restrictions
GET requests are less secure than POST requests
- Q4. What is observer pattern
- Ans.
Observer pattern is a design pattern in which an object maintains a list of its dependents and notifies them automatically of any state changes.
Also known as publish-subscribe pattern
Used in event-driven systems
Allows loose coupling between objects
Example: A weather station broadcasts weather updates to multiple displays
Example: A stock market ticker notifies multiple investors of stock price changes
- Q5. What is singleton
- Ans.
Singleton is a design pattern that restricts the instantiation of a class to a single object.
Singleton ensures that only one instance of a class exists in the entire application.
It provides a global point of access to the instance.
Commonly used in scenarios where a single instance needs to coordinate actions across the system.
Example: Database connection manager, logger, configuration manager.
- Q6. What is immutable in java
- Ans.
Immutable in Java refers to objects whose state cannot be changed after creation.
String, Integer, and other wrapper classes are immutable in Java.
Immutable objects are thread-safe and can be shared without synchronization.
To create an immutable class, make all fields final and private, and don't provide setters.
Examples of immutable classes in Java include LocalDate, LocalTime, and LocalDateTime.
- Q7. How do you create immutable in java
- Ans.
Creating immutable in Java
Use final keyword to make variables immutable
Use private constructor to prevent object modification
Use defensive copying to prevent modification of mutable objects
Use enum to create immutable objects
Use String class to create immutable strings
- Q8. Where have you used immutable in java
- Q9. What is dependency injection
- Ans.
Dependency injection is a design pattern that allows objects to receive dependencies rather than creating them internally.
It helps to decouple the code and makes it more testable and maintainable.
It allows for easier swapping of dependencies without changing the code.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.
Example: Instead of creating a database co...
- Q10. What is CORS
- Ans.
CORS stands for Cross-Origin Resource Sharing. It is a security feature implemented in web browsers to restrict access to resources from different origins.
CORS allows web servers to specify which origins are allowed to access its resources
It is implemented using HTTP headers
CORS prevents malicious websites from accessing sensitive data from other websites
Examples of resources that may be restricted by CORS include cook
- Q11. How do you overcome CORS
- Ans.
CORS can be overcome by configuring the server to allow cross-origin requests.
Configure the server to include the Access-Control-Allow-Origin header
Use JSONP (JSON with Padding) to bypass CORS restrictions
Use a proxy server to make the request on behalf of the client
Use a browser extension to disable CORS restrictions during development
Use a server-side proxy to forward requests to the target server

- Q2. Css box model, difference between padding and margin
- Ans.
Padding is the space inside the border of an element, while margin is the space outside the border.
Padding is used to create space between the content and the border of an element.
Margin is used to create space between the border of an element and other elements.
Padding affects the size of the content area, while margin affects the positioning of the element.

- Q1. Two Sum of numbers with given target value
- Ans.
Given an array of integers, find two numbers that add up to a given target value.
Use a hash map to store the difference between the target value and each element in the array.
Iterate through the array and check if the current element exists in the hash map.
If it does, return the indices of the two numbers.
If no solution is found, return an empty array.
- Q2. Calculate the time taken by kth person to collect n number of tickets
- Ans.
The time taken by the kth person to collect n number of tickets can be calculated using a formula.
Use the formula: time = (n - 1) * k
Subtract 1 from n because the first person doesn't need to wait for anyone
Multiply the result by k to get the time taken by the kth person
Example: If n = 5 and k = 3, the time taken by the 3rd person would be (5 - 1) * 3 = 12
- Q3. Seperation of even and odd numbers
- Ans.
Separate even and odd numbers in an array
Iterate through the array and check if each number is even or odd
Create two separate arrays for even and odd numbers
Add the even numbers to the even array and odd numbers to the odd array
Return both arrays as the result
