In this round, I was first asked a simple coding question related to Linked List and this was later followed by some questions from Java, Java Collections and OOPS.

Q1. 
Reverse Linked List Problem Statement
Given a singly linked list of integers, return the head of the reversed linked list.
Example:
Initial linked list: 1 -> 2 -> 3 -> 4 -> NULL
Reversed link...read more
Ans. 
Reverse a singly linked list of integers and return the head of the reversed linked list.
• Iterate through the linked list and reverse the pointers to point to the previous node instead of the next node.

• Use three pointers to keep track of the current, previous, and next nodes while reversing the linked list.

• Update the head of the reversed linked list as the last node encountered during the reversal process.

Q2. How does ConcurrentHashMap work in Java?
Ans. 
ConcurrentHashMap is a thread-safe implementation of the Map interface in Java.
• ConcurrentHashMap allows multiple threads to read and write to the map concurrently without causing any inconsistencies.

• It achieves thread-safety by dividing the map into segments, each of which can be locked independently.

• ConcurrentHashMap uses a technique called lock striping to minimize contention and improve performance.

• It does not throw...read more

Q3. How many types of memory areas are allocated by the JVM?
Ans. 
JVM allocates 5 types of memory areas: Heap, Stack, Method Area, PC Register, and Native Method Stack.
• Heap is used for storing objects and is shared among all threads.

• Stack is used for storing method calls and local variables, each thread has its own stack.

• Method Area stores class structures, method data, and static variables.

• PC Register stores the address of the currently executing instruction.

• Native Method Stack is u

Q4. Can you differentiate between ArrayList and Vector in Java?
Ans. 
ArrayList is non-synchronized and Vector is synchronized in Java.
• ArrayList is not synchronized, while Vector is synchronized.

• ArrayList is faster than Vector as it is not synchronized.

• Vector is thread-safe, while ArrayList is not.

• Example: ArrayList<String> list = new ArrayList<>(); Vector<String> vector = new Vector<>();

Q5. What is the difference between HashSet and HashMap in Java?
Ans. 
HashSet is a collection of unique elements, while HashMap is a key-value pair collection.
• HashSet does not allow duplicate elements, while HashMap allows duplicate values but not duplicate keys.

• HashSet uses a hash table to store elements, while HashMap uses key-value pairs to store data.

• Example: HashSet<String> set = new HashSet<>(); HashMap<String, Integer> map = new HashMap<>();

Q6. What do you mean by data encapsulation?
Ans. 
Data encapsulation is the concept of bundling data with the methods that operate on that data within a class.
• Data encapsulation restricts access to certain components of an object, protecting the data from external interference.

• It allows for better control over the data by hiding the implementation details and only exposing necessary information through methods.

• Encapsulation helps in achieving data abstraction, where t...read more

Q7. Can static methods be overridden?
Ans. 
No, static methods cannot be overridden in Java.
• Static methods belong to the class itself, not to any specific instance of the class.

• Subclasses can define static methods with the same signature as the parent class, but it is not considered overriding.

• Example: Parent class has a static method 'display()', and subclass also has a static method 'display()'. These are two separate methods, not overriding each other.

This round had questions revolving around Spring Boot and Automation Testing frameworks like Selenium.

Q1. What are the basic annotations that Spring Boot offers?
Ans. 
Spring Boot offers basic annotations like @SpringBootApplication, @RestController, @Autowired, @RequestMapping, @ComponentScan.
• @SpringBootApplication - Used to mark the main class of a Spring Boot application.

• @RestController - Used to define RESTful web services.

• @Autowired - Used for automatic dependency injection.

• @RequestMapping - Used to map web requests to specific handler methods.

• @ComponentScan - Used to specify th

Q2. Can you explain the @RestController annotation in Spring Boot?
Ans. 
The @RestController annotation in Spring Boot is used to define a class as a RESTful controller.
• It is a specialized version of the @Controller annotation that is used to create RESTful web services.

• It eliminates the need for annotating each method with @ResponseBody as it combines @Controller and @ResponseBody annotations.

• It is typically used to build RESTful web services that return JSON or XML data.

• Example: @RestCont...read more

Q3. What is dependency injection?
Ans. 
Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.
• Allows for easier testing by providing mock dependencies

• Promotes loose coupling between components

• Improves code reusability and maintainability

• Examples: Constructor injection, Setter injection, Interface injection

Q4. What does the @SpringBootApplication annotation do internally?
Ans. 
The @SpringBootApplication annotation is used to mark the main class of a Spring Boot application.
• Combines @Configuration, @EnableAutoConfiguration, and @ComponentScan annotations

• Enables the application to start with a main method

• Automatically scans for Spring components in the package and sub-packages

Q5. What is the starter dependency of the Spring Boot module?
Ans. 
The starter dependency of the Spring Boot module is spring-boot-starter-parent.
• The starter dependency provides a set of default configurations and dependencies for Spring Boot applications.

• It helps in reducing the amount of boilerplate code needed to set up a Spring Boot project.

• The spring-boot-starter-parent is typically used as the parent project in a Spring Boot application's pom.xml file.

Q6. Explain the difference between findElement() and findElements() in Selenium.
Ans. 
findElement() returns the first matching element on the web page, while findElements() returns a list of all matching elements.
• findElement() returns a single WebElement matching the locator provided.

• findElements() returns a list of WebElements matching the locator provided.

• If no elements are found, findElement() will throw a NoSuchElementException, while findElements() will return an empty list.

Q7. What are the different types of waits available in Selenium WebDriver?
Ans. 
Different types of waits in Selenium WebDriver include Implicit Wait, Explicit Wait, and Fluent Wait.
• Implicit Wait: Waits for a certain amount of time before throwing a NoSuchElementException.

• Explicit Wait: Waits for a certain condition to occur before proceeding further in the code.

• Fluent Wait: Waits for a condition to be true with a specified polling frequency and timeout.
