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. Choose based on performance needs.
• ArrayList is backed by a dynamic array, allowing fast random access. Example: accessing an element by index is O(1).

• LinkedList consists of nodes that hold data and references to the next and previous nodes, making insertions/deletions O(1) if the node is known.

• ArrayList has a fixed size, and resizing ...read more

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 objects.
• == compares memory addresses (references) of objects.

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

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

• Example: a.equals(b) returns true.

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

• Improper use of == can lead

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 and the Stream API, enhancing functional programming and data processing capabilities.
• Lambdas: Enable concise representation of functional interfaces, e.g., (x, y) -> x + y.

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

• Default Methods: Allow adding new methods to interfaces without breaking exis...read more

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

• Unchecked exceptions are subclasses of RuntimeException.

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

• Example of unchecked exception: NullPointerException, which does not require explicit handling.

• The Java Memory Model (JMM) specifies how threads interact through memory and what behaviors are allowed.

• It ensures visibility of shared variables across threads, preventing stale data issues.

• Synchronization mechanisms (like synchronized blocks) enforce mutual exclusion and visibility.

• 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 methods perform similar functions.

Q1. Explain the difference between ArrayList and LinkedList in Java. When would you choose one over the other?
Ans. 
ArrayList uses a dynamic array for storage, while LinkedList uses a doubly linked list structure.
• 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.

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 simplicity but has limitations compared to ReentrantLock in flexibility and performance.
• Synchronized is easy to use and requires less code, e.g., 'synchronized(this) { ... }'.

• It can lead to thread contention and performance bottlenecks in high-concurrency scenarios.

• Synchronized blocks are not interruptible, meaning a thread cannot be stopped while waiting for a lock.
