  • 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 the actual values of objects.

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

    • Use .equals() to compare the actual values of objects, especially for String comparison.

    • Improper usage can lead to unexpected results, such as comparing memory addresses instead of 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 automatically manages memory by reclaiming unused objects.

    • Java garbage collector runs in the background to identify and remove objects that are no longer needed.

    • Different types of garbage collection algorithms in Java include Serial, Parallel, CMS, G1, and Z Garbage Collector.

    • For example, the Serial garbage collector uses a single thread for garbage collection, while the Parallel garbage coll...

  • 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 'throws'. Example: IOException.

    • Unchecked exceptions do not need to be caught or declared. Example: NullPointerException.

    • Proper handling of exceptions involves using try-catch blocks for c...

  • 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 and how changes made by one thread are visible to others.

    • Java Memory Model ensures that threads have a consistent view of shared memory.

    • It defines the rules for reading and writing variables in a multithreaded environment.

    • Synchronization ensures that only one thread can access a shared resource at a time.

    • Volatile keyword in Java ensures visibility of cha...

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

    Method overloading involves creating multiple methods in the same class with the same name but different parameters. Method overriding involves creating a new implementation of a method in a subclass.

    • Method overloading is used to provide multiple methods with the same name but different parameters, allowing for flexibility in method calls.

    • Method overriding is used to provide a new implementation of a method in a subcla...

  • 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

  • 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 being more declarative and allowing parallel processing.

    • Java Stream is a high-level abstraction over collections that allows for functional-style operations like map, filter, reduce, etc.

    • Streams are more declarative compared to Iterators, which are imperative. This means you specify what you want to do rather th...

  • 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...

  • 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 restrict the user from changing the value of a variable, making it a constant.

    • finally is a block of code that is always executed, whether an exception is thrown or not.

    • 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 within the class itself.

    • Provide a public static method to access the instance, creating it if necessary.

    • Ensure the constructor is private to prevent instantiation from outside the class.

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

  • 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 fair locking mechanisms.

    • ReentrantLock provides tryLock() and lockInterruptibly() methods for more control over locking.

    • Explicit unlocking in ReentrantLock reduces the chance of deadlocks compared to synchronized.
