  • Q3. What is recursion, write a code for it
  • Ans. 

    Recursion is a programming technique where a function calls itself to solve a problem.

    • Recursion involves breaking down a problem into smaller subproblems and solving them recursively.

    • A base case is needed to stop the recursion and prevent infinite loops.

    • Example: Factorial calculation using recursion - function factorial(n) { return n === 0 ? 1 : n * factorial(n-1); }

  • Answered by AI
  • Q4. Why we don't use pointers in java
  • Ans. 

    Java doesn't use pointers for security and simplicity reasons.

    • Java uses references instead of pointers to avoid direct memory manipulation.

    • Pointers can lead to memory leaks and security vulnerabilities.

    • Java's garbage collection manages memory automatically, reducing the need for pointers.

  • Answered by AI
  • Q5. What are the difference between array and arraylist
  • Ans. 

    Array is a fixed-size data structure while ArrayList is a dynamic-size data structure in Java.

    • Array is a fixed-size collection of elements of the same data type, while ArrayList is a dynamic-size collection that can grow or shrink.

    • Arrays can store primitive data types and objects, while ArrayList can only store objects.

    • Arrays require a specified size at the time of declaration, while ArrayList can dynamically resize it...

  • Ans. 

    Lazy loading is a technique used in web development to defer loading non-essential resources until they are needed.

    • Lazy loading helps improve page load times by only loading necessary resources initially.

    • It is commonly used in Angular applications to load modules, components, or routes on demand.

    • Lazy loading can be implemented using Angular's loadChildren property in the routing configuration.

  • Q3. What is switchMap?
  • Ans. 

    switchMap is an operator in RxJS that projects each source value to an Observable which is merged in the output Observable.

    • switchMap is used to switch to a new Observable whenever the source Observable emits a new value.

    • It cancels the previous Observable subscription when a new value is emitted.

    • Example: source$.pipe(switchMap(value => new Observable(value)))

  • Answered by AI
  • Q4. Observables and promises

  • Q7. What is multicasting ?
  • Ans. 

    Multicasting is the process of sending data from one source to multiple destinations simultaneously.

    • In multicasting, a single sender sends data to a group of receivers at the same time.

    • It is commonly used in streaming services where one server sends data to multiple clients.

    • Multicasting is more efficient than unicasting (one-to-one communication) when sending data to multiple recipients.

  • Answered by AI
  • Q8. What is RxJS ?
  • Ans. 

    RxJS is a library for reactive programming using Observables to handle asynchronous data streams.

    • RxJS stands for Reactive Extensions for JavaScript.

    • It allows you to work with asynchronous data streams and events.

    • Operators like map, filter, mergeMap, switchMap, etc., can be used to manipulate and combine streams.

    • Example: Using RxJS to handle HTTP requests in Angular applications.
