10+ Software Development Analyst Interview Questions and Answers

Hashcode is used to calculate the index of an object in a hashmap.

• Hashcode is a unique integer value assigned to an object by the JVM.

• The hashcode value is used to calculate the index of the object in the hashmap.

• The index is calculated using the hashcode value and the size of the hashmap.

• If two objects have the same hashcode value, they will be stored in the same index using linked lists.

Java 8 introduced several new features including lambda expressions, streams, and functional interfaces.

• Lambda expressions allow for functional programming and simplify code.

• Streams provide a way to process collections of data in a functional way.

• Functional interfaces allow for the use of lambda expressions.

• Default methods allow for adding methods to interfaces without breaking existing implementations.

• Date and time API improvements.

• Optional class for null checking.

There is no limit to the number of document ready functions that can be used in a js file.

• Multiple document ready functions can be used to ensure that all necessary elements are loaded before executing code.

• Each document ready function should be enclosed in its own set of parentheses.

• It is important to avoid nesting document ready functions within each other.

• Example: $(document).ready(function() { //code }); $(document).ready(function() { //code });

SPFx is used in SharePoint for building web parts and extensions. jQuery and JSOM are used for client-side development. JavaScript, CSS, and HTML are essential for front-end development.

• SPFx is used to create web parts and extensions in SharePoint.

• jQuery is used for DOM manipulation and event handling.

• JSOM (JavaScript Object Model) is used for interacting with SharePoint data on the client side.

• JavaScript is used for adding interactivity to web pages.

• CSS is used for styling w...read more

Secure web methods, APIs, and controllers by implementing authentication, authorization, and encryption.

• Implement authentication to verify the identity of the user or application accessing the resource.

• Implement authorization to control access to specific resources based on user roles or permissions.

• Use encryption to protect sensitive data transmitted over the network.

• Implement rate limiting to prevent denial of service attacks.

• Use HTTPS instead of HTTP to encrypt all data tr...read more

Using recursion to print a series of numbers without using a loop.

• Create a recursive function that takes the starting number and the ending number as parameters.

• Print the starting number and recursively call the function with starting number + 1 until it reaches the ending number.

• Example: function printNumbers(start, end) { if(start <= end) { console.log(start); printNumbers(start + 1, end); } }

Printing natural numbers and AP series using logic.

• To print all natural numbers, start from 1 and increment by 1 in a loop until the desired limit.

• For AP series, start with the first term and add the common difference in each iteration.

• Example: Natural numbers - 1, 2, 3, 4, 5... AP series - 2, 4, 6, 8, 10...

HashMap allows null values and keys, while Hashtable does not. HashMap is not synchronized, Hashtable is synchronized.

• HashMap allows null values and keys, while Hashtable does not

• HashMap is not synchronized, Hashtable is synchronized

• HashMap is faster than Hashtable

A functional interface is an interface with a single abstract method, enabling lambda expressions in Java.

• A functional interface can have multiple default or static methods.

• Example: Runnable is a functional interface with a single method run().

• Functional interfaces are used primarily in lambda expressions and method references.

• Common functional interfaces include Predicate, Function, and Consumer.

Abstraction is a fundamental concept in software development that simplifies complex systems by hiding unnecessary details.

• It allows developers to focus on high-level functionalities without worrying about implementation specifics.

• Example: In a car, the driver uses the steering wheel and pedals without needing to understand the engine mechanics.

• In programming, an abstract class can define methods that must be implemented by subclasses, hiding the complexity of the implementat...read more
