    • ArrayList uses an array to store elements, allowing for fast random access but slower insertions and deletions.

    • LinkedList uses nodes with references to the next and previous nodes, making insertions and deletions faster but random access slower.

    • Example: Use ArrayList when you need to frequently access elements by index,...

Interview Preparation Tips

Interview preparation tips for other job seekers - If you have declined JPMC's offer in last 2 years. You would be in cooling off period. I had declined their offer last year for genuine personal reason and not on the last min.
So when I cracked all round with amazing feedbacks and even after compensation discussions happened. After 2 months long process, I was told that they can't role out my offer letter because I am in that 2 years cooling period!!
The central hiring process of the company should not allow applicant to apply if such policies are in place. How would an applicant know that they are in cooling period? The policies are for HRs and recruiters to know. But sadly none of them were aware and ended up wasting my 2 months!! Very disappointed!

This round focused more on Multithreading concepts from Java and also some core concepts from OOPS.

  • Q1. What is a thread in Java?
  • Ans. 

    A thread in Java is a lightweight sub-process that allows concurrent execution within a single process.

    • Threads allow multiple tasks to be executed concurrently in a Java program.

    • Each thread has its own stack and program counter, but share the same memory space.

    • Threads can be created by extending the Thread class or implementing the Runnable interface.

    • Example: Thread t1 = new Thread(new MyRunnable()); t1.start();

  • Answered by AI
  • Q2. What are the start() and run() methods of the Thread class in Java?
  • Ans. 

    The start() method is used to start a new thread, while the run() method contains the code that will be executed by the thread.

    • start() method is used to start a new thread and calls the run() method internally

    • run() method contains the code that will be executed by the thread

    • It is recommended to override the run() method with the desired functionality

  • Answered by AI
  • Q3. What is the difference between the Thread class and the Runnable interface when creating a thread in Java?
  • Ans. 

    Thread class is a class in Java that extends the Thread class, while Runnable interface is an interface that implements the run() method.

    • Thread class extends the Thread class, while Runnable interface implements the run() method.

    • A class can only extend one class, so using Runnable interface allows for more flexibility in the class hierarchy.

    • Using Runnable interface separates the task from the thread, promoting better d...

  • Q4. What is the difference between an abstract class and an interface in OOP?
  • Ans. 

    Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

    • Abstract class can have constructor, fields, and methods, while interface cannot have any implementation.

    • A class can only extend one abstract class, but can implement multiple interfaces.

    • Abstract classes are used to define common behavior among subclasses, while interfaces are used to define a contract for cla...

  • Q5. What is the garbage collector in Java?
  • Ans. 

    Garbage collector in Java is a built-in mechanism that automatically manages memory by reclaiming unused objects.
