FAQ

What are the key differences between an abstract class and an interface in Java?

+

An abstract class can have both abstract and concrete methods, and can hold state (fields), whereas an interface can only have abstract methods (until Java 8 introduced default methods) and cannot hold state. A class can inherit only one abstract class but can implement multiple interfaces.

How does the Java garbage collector work, and why is it important?

+

The Java garbage collector automatically identifies and disposes of objects that are no longer reachable to free up memory. It helps in efficient memory management and prevents memory leaks, which is crucial for long-running applications like those in banking systems.

Explain how you would handle concurrency issues in a multithreaded Java application.

+

Handling concurrency issues involves using synchronization mechanisms like the synchronized keyword, locks (e.g., ReentrantLock), and concurrent collections. Proper thread coordination techniques such as wait/notify or using higher-level concurrency APIs help prevent race conditions and deadlocks.

Can you describe the Spring framework and its benefits in Java development?

+

Spring is a popular Java framework that provides comprehensive infrastructure support for developing Java applications. It facilitates dependency injection, aspect-oriented programming, and simplifies building applications with features like MVC architecture, transaction management, and integration with various data access technologies.

What strategies do you use to optimize SQL queries in a Java application?

+

Optimizing SQL queries involves indexing relevant columns, avoiding unnecessary columns in SELECT statements, using prepared statements to improve performance and security, analyzing query execution plans, and minimizing the use of nested queries or joins where possible.

How would you explain the concept of microservices and their advantages over monolithic architectures?

+

Microservices architecture decomposes an application into small, independent services that communicate over APIs. Advantages include improved scalability, easier maintenance, independent deployment cycles, and greater fault isolation compared to monolithic architectures where all components are tightly coupled.

Describe a challenging bug you encountered in Java and how you resolved it.

+

A response would vary, but the ideal answer explains the debugging process, tools used (like debuggers or logs), root cause analysis, and the fix implemented, demonstrating problem-solving skills and persistence.

What is the difference between HashMap and ConcurrentHashMap in Java?

+

HashMap is not thread-safe and can cause concurrency issues if accessed by multiple threads simultaneously. ConcurrentHashMap is designed for concurrent access, allowing safe operations by multiple threads without external synchronization.

What are the key differences between Java 8 and Java 11?

+

Java 8 introduced features like lambda expressions, the Stream API, and the new Date and Time API. Java 11, on the other hand, introduced features like the new HTTP Client API, the new Epsilon garbage collector, and the removal of the Java EE and CORBA modules.

Explain the concept of functional interfaces in Java.

+

A functional interface in Java is an interface that contains only one abstract method. Functional interfaces are used to define the type of lambda expressions and method references. The @FunctionalInterface annotation is used to indicate that an interface is a functional interface.
