Java has introduced several new features in recent versions.
Java 8 introduced lambda expressions, which allow for functional programming.
Java 8 also introduced the Stream API for processing collections of data.
Java 9 introduced the module system, which provides better encapsulation and modularity.
Java 10 introduced local variable type inference, allowing the omission of explicit type declarations.
Java 11 introduced the...
The @Component and @Repository annotations are used in Spring Framework for different purposes.
Both annotations are used to define beans in the Spring container.
@Component is a generic stereotype annotation for any Spring-managed component.
@Repository is a specialization of @Component used for DAO classes.
The @Repository annotation provides additional exception translation for data access exceptions.
Using @Repository i...
The @Entity annotation is used in Java to mark a class as an entity, which represents a table in a relational database.
The @Entity annotation is part of the Java Persistence API (JPA) and is used in object-relational mapping (ORM) to map Java objects to database tables.
It is typically used in conjunction with other JPA annotations like @Table, @Column, and @Id.
The @Entity annotation is used to define the entity name, s...
The database is configured by setting up the necessary parameters and configurations to ensure proper functioning and performance.
Database configuration involves defining the database schema, tables, and relationships.
It includes setting up indexes and constraints for data integrity.
Configuring database security measures like user access control and permissions.
Tuning database performance by optimizing query execution ...
Dockerfile is a text file that contains instructions to build a Docker image.
Dockerfile is used to automate the creation of Docker images.
It specifies the base image, dependencies, environment variables, and commands to run.
Each instruction in the Dockerfile creates a new layer in the image.
Dockerfile can be version controlled and shared to ensure consistent builds.
Example: FROM ubuntu:latest RUN apt-get update && apt-...
CI/CD is a software development practice that enables frequent and automated code integration, testing, and deployment.
CI/CD stands for Continuous Integration and Continuous Deployment.
It involves automating the process of integrating code changes, running tests, and deploying the application.
CI/CD helps in reducing manual errors, improving code quality, and increasing development speed.
Tools like Jenkins, GitLab CI/CD...
Mutable classes in Java are classes whose state can be modified after creation.
Mutable classes allow changing their internal state
They can have mutable fields or methods that modify their state
To create a mutable class, define fields with non-final modifiers
Provide public methods to modify the state of the class

It was a technical interview round where I was asked questions based on DSA.
I explained to him the brute force approach as well as the optimal approach, after which he asked me to write the code for the optimal approach. He asked me to write the code from scratch, so first I wrote the code to insert the nodes in the linked list and then the code to detect a loop in the linked list.
This was quite an easy question. The interviewer asked me to write the code to check whether the kth bit of an integer is set or not, and then make some changes in that code to check whether the kth bit of an integer is unset or not.
Round duration - 30 minutes

Tip 1 : For DSA questions in interviews, start explaining from the brute force approach and then move to the optimal one. Convey your thought process to the interviewers, so that they can help you out if you get stuck. Communication skills matter a lot, and I think that is what makes the difference!
Tip 2 : Do some research about the company you are interviewing for and prepare the answers to the questions like Why should we hire you? (frame your answer in such a way that shows that your career goals align with the goals of the company), Why XYZ company?, Competitors of XYZ, etc. beforehand. Read about some latest news related to the company so that you can ask questions based upon that when the interviewer allows you to ask any question. This shows that you are genuinely interested to work for the company.
Tip 3 : Spend proper time making your resume and get it reviewed by seniors. Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it. The interviewers are much much experienced than you and they’ll catch you easily if you lie. So don’t take risks here.
Tip 1 : Try to include at least 1 development project in your resume.
Tip 2 : Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it.
