Round 1 - Interview Questions 

(20 Questions)

  • Q1. Explain the difference between ArrayList and LinkedList in Java. When would you choose one over the other?
  • Ans. 

    ArrayList is a resizable array, while LinkedList is a doubly linked list. Choose based on performance needs.

    • ArrayList: Faster for random access (O(1)). Example: list.get(5);

    • LinkedList: Faster for insertions/deletions (O(1)) at both ends. Example: list.addFirst('A');

    • ArrayList: Uses less memory overhead compared to LinkedList.

    • LinkedList: Better for frequent insertions/deletions in the middle of the list.

    • ArrayList: Requir...

  • Q3. What is the difference between == and .equals() in Java? When should each be used, and what issues can arise from improper usage?
  • Ans. 

    == checks reference equality, while .equals() checks value equality in Java. Use .equals() for content comparison.

    • == compares object references (memory addresses). Example: String a = new String('test'); String b = new String('test'); a == b returns false.

    • .equals() compares actual content of objects. Example: a.equals(b) returns true.

    • Use == for primitive types (int, char, etc.) and .equals() for objects.

    • Improper use of...

  • Q4. How does the Java garbage collector work? Can you describe the different types of garbage collection algorithms available in Java?
  • Ans. 

    Java's garbage collector automatically manages memory by reclaiming unused objects, improving performance and preventing memory leaks.

    • Garbage Collection (GC) is the process of automatically identifying and disposing of objects that are no longer needed.

    • Java uses several GC algorithms, including Serial, Parallel, CMS (Concurrent Mark-Sweep), and G1 (Garbage-First).

    • The Serial GC is a simple, single-threaded collector sui...

  • Q5. What are the main features of Java 8? Can you explain how lambdas and the Stream API have changed the way Java applications are written?
  • Ans. 

    Java 8 introduced lambdas, Stream API, and other features that enhance functional programming and improve code readability.

    • Lambdas: Enable concise representation of functional interfaces. Example: (x, y) -> x + y.

    • Stream API: Allows processing sequences of elements (collections) in a functional style. Example: list.stream().filter(x -> x > 10).collect(Collectors.toList()).

    • Default Methods: Interfaces can have me...

  • Q6. Describe the differences between checked and unchecked exceptions in Java. Provide examples and explain how to handle them properly.
  • Ans. 

    Checked exceptions must be declared or handled; unchecked exceptions do not require explicit handling.

    • Checked exceptions are subclasses of Exception but not of RuntimeException.

    • Example of checked exception: IOException, which must be caught or declared.

    • Unchecked exceptions are subclasses of RuntimeException.

    • Example of unchecked exception: NullPointerException, which does not need to be declared.

  • Q7. What is the Java Memory Model, and how does it affect multithreading and synchronization? How does volatile help ensure memory visibility?
  • Ans. 

    The Java Memory Model defines how threads interact through memory, ensuring visibility and ordering of shared variables.

    • The Java Memory Model (JMM) specifies how threads interact with memory, ensuring consistency and visibility of shared variables.

    • It defines rules for visibility, atomicity, and ordering of operations in a multithreaded environment.

    • Without proper synchronization, threads may see stale or inconsistent da...

  • Q8. Can you explain the difference between method overloading and method overriding in Java? Provide examples where each should be used.
  • Ans. 

    Method overloading allows multiple methods with the same name but different parameters; overriding allows subclass methods to replace superclass methods.

    • Method Overloading: Same method name, different parameter types or counts.

    • Example of Overloading: 'int add(int a, int b)' and 'double add(double a, double b)'.

    • Use Overloading for convenience and readability when performing similar operations.

    • Method Overriding: Same met...

  • Q9. What are functional interfaces in Java? How do they work with lambda expressions? Provide an example of a custom functional interface.
  • Ans. 

    Functional interfaces in Java are interfaces with a single abstract method, enabling lambda expressions for concise code.

    • A functional interface has exactly one abstract method.

    • They can have multiple default or static methods.

    • Common examples include Runnable, Callable, and Comparator.

    • Lambda expressions provide a clear and concise way to implement functional interfaces.

    • Example of a custom functional interface: @Functiona...

  • Q10. What is a Java Stream, and how does it differ from an Iterator? Explain how Streams can be used to process collections efficiently.
  • Ans. 

    Java Streams provide a functional approach to processing sequences of elements, unlike Iterators which are imperative.

    • Streams are part of the Java 8+ API, enabling functional-style operations on collections.

    • Unlike Iterators, Streams do not store data; they process data on-the-fly.

    • Streams support operations like map, filter, and reduce, allowing for concise and readable code.

    • Example: List<String> names = Arrays.as...

  • Q11. Explain the concept of immutability in Java. How does the String class achieve immutability, and what are the advantages of immutable objects?
  • Ans. 

    Immutability in Java means objects cannot be modified after creation, enhancing security and performance.

    • 1. Immutability: Once created, an object's state cannot be changed.

    • 2. String Class: Strings in Java are immutable; any modification creates a new String object.

    • 3. Example: String s1 = "Hello"; s1 = s1 + " World!"; // s1 now points to a new String object.

    • 4. Advantages: Thread-safe, easier to cache, and can be used as...

  • Q12. What is the difference between final, finally, and finalize in Java? Provide examples to illustrate their usage.
  • Ans. 

    final, finally, and finalize serve different purposes in Java: variable declaration, exception handling, and garbage collection respectively.

    • final: Used to declare constants. Example: final int MAX_VALUE = 100;

    • finally: Block that executes after try-catch, regardless of exceptions. Example: try { ... } catch { ... } finally { ... }

    • finalize: Method called by the garbage collector before an object is removed. Example: pro

  • Q13. Explain the Singleton design pattern in Java. How can you implement it safely to ensure thread safety?
  • Ans. 

    The Singleton pattern restricts instantiation of a class to one object, ensuring controlled access to that instance.

    • 1. The Singleton pattern ensures a class has only one instance and provides a global point of access to it.

    • 2. Common implementations include lazy initialization, eager initialization, and double-checked locking.

    • 3. Lazy initialization: Create the instance when it is needed, using synchronized method for th...

  • Q14. What are Java annotations, and how are they used in frameworks like Spring? Explain the difference between built-in and custom annotations.
  • Ans. 

    Java annotations provide metadata for classes, methods, and fields, enhancing functionality in frameworks like Spring.

    • Annotations are metadata that provide information about the program but are not part of the program itself.

    • In Spring, annotations like @Component, @Service, and @Controller are used for defining beans and their roles.

    • Built-in annotations include @Override, @Deprecated, and @SuppressWarnings, which serve...

  • Q15. How do Java Streams handle parallel processing? What are the potential pitfalls of using parallel streams, and how can they be mitigated?
  • Ans. 

    Java Streams enable parallel processing for efficient data handling but come with potential pitfalls that need careful management.

    • Java Streams can be processed in parallel using the 'parallelStream()' method, which divides the workload across multiple threads.

    • Parallel streams utilize the Fork/Join framework, allowing tasks to be split and executed concurrently, improving performance for large datasets.
