Essential Interview Questions For Software Engineering Systems Information Technology Specialist
1. What is the difference between a class and an interface in Java?
- A class is a blueprint for creating objects, while an interface is a contract that defines the behavior of a class.
- A class can have a state (data members) and behavior (methods), while an interface can only have behavior.
- A class can inherit from another class, while an interface can only extend other interfaces.
- A class can implement multiple interfaces, while an interface can only extend multiple interfaces.
2. Explain the concept of polymorphism in Java.
Method Overloading
- Having multiple methods in the same class with the same name but different parameters.
- The compiler determines which method to call based on the number and types of arguments passed.
Method Overriding
- Having methods with the same name and parameters in a subclass and its superclass.
- The subclass’s method overrides the superclass’s method.
3. What is the difference between a checked exception and an unchecked exception in Java?
- Checked exceptions are exceptions that must be handled by the programmer or propagated to the caller.
- Unchecked exceptions are exceptions that are not required to be handled by the programmer.
- Checked exceptions are typically caused by errors in the program logic, while unchecked exceptions are typically caused by runtime errors.
4. Explain the purpose of a thread pool in Java.
- To manage the creation and execution of threads.
- To improve performance by reusing existing threads instead of creating new ones.
- To control the number of concurrent threads to prevent resource exhaustion.
5. What is the significance of immutability in Java?
- Ensures that an object’s state cannot be modified after creation.
- Makes objects thread-safe and easier to reason about.
- Improves performance by eliminating the need for synchronization.
6. Explain the concept of garbage collection in Java and how it helps in memory management.
- Garbage collection is an automatic process that reclaims memory occupied by objects that are no longer referenced.
- The Java Virtual Machine (JVM) has a garbage collector that runs periodically to identify and remove unreachable objects.
- Garbage collection helps prevent memory leaks and improves program stability.
7. What are the advantages of using a relational database management system (RDBMS) like MySQL?
- Structured data storage and management.
- Support for ACID (Atomicity, Consistency, Isolation, Durability) properties.
- Data integrity and consistency through constraints.
- Efficient query processing and data retrieval.
8. Explain the concept of RESTful API and its benefits.
- A style of software architecture for designing web services.
- Uses a set of constraints to ensure uniformity and interoperability.
- Benefits: Scalability, Flexibility, Caching, Statelessness.
9. What are the key components of a software development life cycle (SDLC)?
- Requirements Gathering
- Design
- Implementation
- Testing
- Deployment
- Maintenance
10. Describe the Agile methodology and its advantages in software development.
- An iterative and incremental approach to software development.
- Emphasizes close collaboration between development teams and stakeholders.
- Advantages: Flexibility, Adaptability, Increased Productivity, Reduced Risks.
