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 and LinkedList are both classes in Java that implement the List interface, but they have different underlying data structures.

    • ArrayList uses a dynamic array to store elements, providing fast random access but slower insertion and deletion.

    • LinkedList uses a doubly linked list to store elements, providing fast insertion and deletion but slower random access.

    • Choose ArrayList when you need fast random access and ...

  • 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, == compares memory addresses while .equals() compares values of objects. Improper usage can lead to unexpected results.

    • Use == to compare primitive data types or check if two objects reference the same memory address.

    • Use .equals() to compare the values of objects, such as strings or custom classes.

    • Improper usage of == with objects can lead to unexpected results as it compares memory addresses, not values.

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

    The Java garbage collector is responsible for automatically managing memory by reclaiming unused objects.

    • The garbage collector in Java runs in the background and automatically reclaims memory from objects that are no longer in use.

    • There are different types of garbage collection algorithms in Java, such as Serial, Parallel, CMS, G1, and ZGC.

    • Each garbage collection algorithm has its own characteristics and is suitable fo

    • Stream API provides a way to process collections of objects in a functional style, making code more expressive and efficient.

    • Java 8 also introduced default methods in interfaces, allowing for backward compatib...

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

    Checked exceptions are checked at compile time, while unchecked exceptions are not. Proper handling involves either catching or declaring the exception.

    • Checked exceptions must be either caught or declared in the method signature using the 'throws' keyword.

    • Unchecked exceptions do not need to be caught or declared, but can still be handled using try-catch blocks.

    • Examples of checked exceptions include IOException and Clas...

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

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

    Method overloading is when multiple methods have the same name but different parameters, while method overriding is when a subclass provides a specific implementation of a method in its superclass.

    • Method overloading is achieved within the same class by having multiple methods with the same name but different parameters.

    • Method overriding occurs in a subclass that provides a specific implementation of a method that is al...

  • 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. They can be used with lambda expressions for functional programming.

    • Functional interfaces have only one abstract method, but can have multiple default or static methods.

    • Lambda expressions can be used to implement the abstract method of a functional interface concisely.

    • An example of a custom functional interface is 'Calculator' with a single abs

  • Answered by AI
  • 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 Stream is a sequence of elements that supports functional-style operations. It differs from Iterator by allowing for more concise and declarative code.

    • Streams can process elements in a collection in a declarative way, allowing for functional-style operations like map, filter, and reduce.

    • Streams do not store elements, they operate on the source data structure (e.g., List) directly.

    • Iterators are used to iterate over...

  • Answered by AI
  • 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. String class achieves immutability by not allowing changes to its value.

    • Immutability means once an object is created, its state cannot be changed.

    • String class achieves immutability by making its value final and not providing any methods to modify it.

    • Advantages of immutable objects include thread safety, caching, and easier debugging.

    • Example: String s...

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

    final, finally, and finalize have different meanings in Java.

    • final is a keyword used to declare constants, immutable variables, or prevent method overriding.

    • finally is a block used in exception handling to execute code after try-catch block.

    • finalize is a method used for cleanup operations before an object is garbage collected.

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

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

    • Create a private static instance of the class.

    • Provide a public static method to access the instance.

    • Use synchronized keyword or double-checked locking to ensure thread safety.

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

  • Q17. What are the advantages and disadvantages of using Java’s synchronized keyword for thread synchronization? The synchronized keyword ensures that only one thread can access a block of code at a time. It pr...
  • Ans. 

    ReentrantLock should be used instead of synchronized when more flexibility and control over locking mechanisms is needed.

    • Use ReentrantLock when you need to implement custom locking strategies or require advanced features like tryLock() and lockInterruptibly()

    • ReentrantLock supports fair locking mechanisms, ensuring that threads acquire the lock in the order they requested it
