  • Q1. Can you explain the SOLID principles in Object Oriented Design?
  • Ans. 

    SOLID principles are a set of five design principles in object-oriented programming to make software more maintainable, flexible, and scalable.

    • Single Responsibility Principle (SRP) - A class should have only one reason to change.

  • Q2. What is abstraction in Object-Oriented Programming?
  • Ans. 

    Abstraction in OOP is the concept of hiding complex implementation details and showing only the necessary features to the outside world.

    • Abstraction allows us to focus on what an object does instead of how it does it

    • It helps in reducing complexity and improving maintainability of code

    • Example: In a car, we don't need to know the internal workings of the engine to drive it

  • Answered by AI
  • Q3. How is an abstract class different from an interface?
  • Ans. 

    Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

    • Abstract class can have constructors, fields, and methods with implementation.

    • Interface can only have abstract methods and constants.

    • A class can implement multiple interfaces but can only inherit from one abstract class.

    • Example: Abstract class - Animal with abstract method 'eat', Interface - Flyable with metho

  • Q4. What is a classloader in Java?
  • Ans. 

    A classloader in Java is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine.

    • Classloaders are responsible for loading classes at runtime based on the fully qualified name of the class.

    • There are different types of classloaders in Java such as Bootstrap Classloader, Extension Classloader, and Application Classloader.

    • Classloaders follow a delegation model where a classl...

  • Answered by AI
  • Q5. 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
  • Q6. Can you tell us something about the JIT compiler?
  • Ans. 

    JIT compiler stands for Just-In-Time compiler, which dynamically compiles and optimizes code during runtime.

    • JIT compiler is used to improve the performance of applications by compiling code at runtime instead of ahead of time.

    • It converts bytecode into native machine code on-the-fly, allowing for faster execution.

    • Examples of JIT compilers include HotSpot for Java and V8 for JavaScript.

  • Answered by AI
  • Q7. Can you explain what a thread pool is?
  • Ans. 

    A thread pool is a collection of worker threads that are used to execute tasks concurrently.

    • Thread pools help manage and reuse threads to improve performance and reduce overhead.

    • They limit the number of concurrent threads to prevent resource exhaustion.

    • Tasks are submitted to the pool and executed by available threads.

    • Example: Java's Executor framework provides implementations of thread pools like ThreadPoolExecutor.

  • Answered by AI
  • Q8. What is the difference between the interrupted() and isInterrupted() methods in Java?
  • Ans. 

    interrupted() checks if the current thread has been interrupted, while isInterrupted() checks if a thread has been interrupted.

    • interrupted() is a static method in the Thread class, while isInterrupted() is an instance method.

    • interrupted() clears the interrupted status of the current thread, while isInterrupted() does not.

    • Example: Thread.currentThread().interrupt(); System.out.println(Thread.interrupted()); // prints tr...

    • Singleton scope creates a single instance per Spring IoC container.

    • Prototype scope creates a new instance every time the bean is requested.

    • Request scope creates a new instance for each HTTP request.

    • Session scope creates a single instance per HTTP session.

    • Application scope creates a single instance per ServletContext.

  • Ans. 

    Autowiring in Spring Boot is a way to automatically inject dependencies into a Spring bean.

    • There are different modes of autowiring in Spring: 'byName', 'byType', 'constructor', 'autodetect', and 'no'.

    • For example, in 'byName' autowiring, Spring looks for a bean with the same name as the property being autowired

  • Ans. 

    Hibernate provides various concurrency strategies like optimistic locking, pessimistic locking, and versioning.

    • Optimistic locking: Allows multiple transactions to read a row simultaneously, but only one can update it at a time. Uses versioning or timestamp to check for conflicts.

    • Pessimistic locking: Locks the row for exclusive use by one transaction, preventing other transactions from accessing it until the lock is rel...

  • Q7. Can you explain the working of Microservice Architecture?
  • Ans. 

    Microservice architecture is an architectural style that structures an application as a collection of loosely coupled services.

    • Microservices are small, independent services that work together to form a complete application.

    • Each microservice is responsible for a specific business function and can be developed, deployed, and scaled independently.

    • Communication between microservices is typically done through APIs.
