Lowe's Interview Questions and Answers

Spring Boot simplifies CRUD operations with RESTful APIs, allowing easy data manipulation using JPA and Hibernate.

• 1. Set up Spring Boot project with dependencies: Spring Web, Spring Data JPA, and a database (e.g., H2, MySQL).

• 2. Create an entity class (e.g., `User`) with annotations like `@Entity`, `@Id`, and `@GeneratedValue`.

• 3. Develop a repository interface (e.g., `UserRepository`) extending `JpaRepository` for ...read more

Binary search is an efficient algorithm for finding an item from a sorted list by repeatedly dividing the search interval in half.

• Requires a sorted array to function correctly.

• Starts by comparing the target value to the middle element of the array.

• If the target is equal to the middle element, the search is complete.

• If the target is less than the middle element, search the left half.

• If the target is greater, search...read more

Creating MVC endpoints in Java involves defining controllers, models, and views for handling requests and responses.

• Define a Controller class annotated with @Controller to handle web requests.

• Use @RequestMapping to map HTTP requests to specific handler methods.

• Create Model classes to represent data and use @ModelAttribute to bind data to the model.

• Return views using ModelAndView or simply return a String represent...read more

Data structures and algorithms related to string manipulation in Java.

• Use built-in methods like indexOf(), substring(), and charAt() for string manipulation.

• Implement algorithms like string reversal, palindrome check, and string matching using DSA concepts.

• Consider using data structures like arrays, hashmaps, and linked lists for efficient string operations.

SQL normalization is the process of organizing a database to reduce redundancy and improve data integrity.

• Normalization involves breaking down a database into smaller, more manageable tables.

• It helps in reducing data redundancy by storing data in a structured manner.

• Normalization ensures data integrity by minimizing anomalies like insertion, update, and deletion anomalies.

• There are different normal forms like 1NF,...read more

HashMap is a data structure that stores key-value pairs for efficient data retrieval.

• HashMap allows O(1) average time complexity for insertions and lookups.

• It uses a hash function to compute an index for storing values.

• Example: Inserting a key-value pair like ('apple', 1) allows quick access via 'apple'.

• Collisions are handled using techniques like chaining or open addressing.
