  • 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.

    • POST requests have no length restrictions

    • GET requests are less secure than POST requests

  • Answered by AI
  • 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

  • Answered by AI
  • 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.

  • Answered by AI

  • Ans. 

    Immutable in Java refers to objects whose state cannot be changed after creation.

    • String, Integer, and other wrapper classes are immutable in Java.

    Creating immutable in Java

    • Use final keyword to make variables immutable

    • There are three types of dependency injection: constructor injection, setter injection, and interface injection.

    • Example: Instead of creating a database co...

  • Answered by AI
  • 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.

  • 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
