In this round, I was first asked about the projects that I worked on in my previous company. I was also asked about the various tech stacks that I was familiar with and then the interviewer started asking me questions around Java and some basic OOPS concepts.

  • Q1. What are the advantages of using Packages in Java?
  • Ans. 

    Packages in Java help organize code, prevent naming conflicts, and provide access control.

    • Organizes code into logical groups for easier maintenance and readability

    • Prevents naming conflicts by allowing classes with the same name to coexist in different packages

    • Provides access control by using access modifiers like public, private, protected, and default

    • Facilitates reusability by allowing classes in one package to be acc...

  • Answered by AI
  • Q2. Why is Java considered platform independent, while the Java Virtual Machine (JVM) is platform dependent?
  • Ans. 

    Java is platform independent because it compiles code into bytecode that can run on any system with a JVM, which is platform dependent.

    • Java code is compiled into bytecode, which is platform independent

    • The JVM interprets the bytecode and translates it into machine code specific to the underlying platform

    • This allows Java programs to run on any system with a JVM installed, making Java platform independent

  • Answered by AI
  • Q3. Why are Java Strings immutable in nature?
  • Ans. 

    Java Strings are immutable to ensure thread safety, security, and optimization.

    • Immutable strings prevent accidental changes, ensuring data integrity.

    • String pool optimization reduces memory usage by reusing common strings.

    • Thread safety is guaranteed as strings cannot be modified concurrently.

    • Security is enhanced as sensitive information cannot be altered once set.

  • Answered by AI
  • Q4. What do you know about the JIT compiler?
  • Ans. 

    JIT compiler stands for Just-In-Time compiler, which compiles code during runtime instead of ahead of time.

    • JIT compiler improves performance by compiling code on-the-fly as it is needed

    • It can optimize code based on runtime conditions and platform specifics

    • Examples include Java's HotSpot JIT compiler and .NET's RyuJIT compiler

  • Answered by AI
  • Q5. Can you differentiate between ArrayList and Vector in Java?
  • Ans. 

    ArrayList is non-synchronized and faster, while Vector is synchronized and slower.

    • ArrayList is not synchronized, while Vector is synchronized.

    • ArrayList is faster than Vector due to lack of synchronization.

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

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

  • Answered by AI
  • Q2. What is the garbage collector in Java?
  • Ans. 

    Garbage collector in Java is a built-in mechanism that automatically manages memory by reclaiming unused objects.

    • Garbage collector runs in the background to identify and remove objects that are no longer needed.

    • It helps prevent memory leaks and optimize memory usage.

    • Examples of garbage collectors in Java include Serial, Parallel, CMS, and G1.

  • Answered by AI
  • Q3. What does the @SpringBootApplication annotation do internally?
  • Ans.

  • Answered by AI
  • Q4. What is dependency injection?
  • Ans. 

    Dependency injection is a design pattern where components are provided with 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

  • Answered by AI
  • Q5. What are the basic annotations that Spring Boot offers?

  • Ans. 

    The command to import a pre-exported Docker image into another Docker host is 'docker load'

    • Use the 'docker load' command followed by the file path of the exported image tarball to import it into the Docker host

    • For example, 'docker load < my_image.tar.gz' will import the image from the file 'my_image.tar.gz'

    • Ensure that you have the necessary permissions to access the file and import images on the target Docker host

  • Answered by AI
  • Q8. Can you describe the lifecycle of a Docker container?
  • Ans.
