I appeared for an interview in Feb 2025, where I was asked the following questions.

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

    ArrayList uses dynamic arrays, while LinkedList uses doubly linked nodes for storage and access.

    • ArrayList provides fast random access (O(1)) due to its underlying array structure.

    • LinkedList allows for efficient insertions and deletions (O(1)) at both ends and in the middle.

    • ArrayList has a fixed size, requiring resizing (O(n)) when capacity is exceeded, while LinkedList grows dynamically.

    • Example: Use ArrayList for frequ...

  • Q2. What are the advantages and disadvantages of using Java’s synchronized keyword for thread synchronization? Can you explain how the ReentrantLock compares to synchronized?
  • Ans. 

    Java's synchronized keyword offers thread safety but has limitations compared to ReentrantLock.

    • Advantages of synchronized: Simple to use and understand.

    • Disadvantages of synchronized: Can lead to thread contention and performance issues.

    • ReentrantLock allows more flexibility, such as tryLock() and timed lock attempts.

    • ReentrantLock can be used for fair locking, preventing thread starvation.

    • Synchronized blocks are tied to ...

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

    In Java, '==' checks reference equality, while '.equals()' checks value equality. Use them appropriately to avoid bugs.

    • == compares object references, checking if both point to the same memory location.

    • Example: String a = new String('test'); String b = new String('test'); a == b returns false.

    • .equals() compares the actual content of the objects.

    • Example: a.equals(b) returns true because the content is the same.

    • Use '==' f...

  • Q4. How does the Java garbage collector work? Can you describe the different types of garbage collection algorithms available in Java?
    • Add your answer
  • 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 simplify code.

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

    • Stream API: Facilitates functional-style operations on collections. Example: list.stream().filter(x -> x > 10).collect(Collectors.toList()).

    • Default Methods: Allow adding new methods to interfaces without breakin...

  • 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, while unchecked exceptions do not require explicit handling.

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

    • Example: IOException, SQLException are checked exceptions.

    • Unchecked exceptions are subclasses of RuntimeException.

    • Example: NullPointerException, ArrayIndexOutOfBoundsException are unchecked exceptions.

    • Checked exceptions must be caught or d...

  • 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.

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

    • Synchronization mechanisms (like synchronized blocks) ensure that only one thread can access...

  • 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 redefines a method in a subclass.

    • Method Overloading: Same method name, different parameters (type, number, or both).

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

    • Use Overloading for convenience and readability when methods perform similar functions.

    • Method Overriding: Redefining a meth...
