Java is a high-level programming language known for its portability and object-oriented programming support. OOPs stands for Object-Oriented Programming. HashMap and HashSet are both data structures in Java, but HashMap is used to store key-value pairs while HashSet is used to store unique elements.

Collection framework in Java is a set of classes and interfaces that provide a way to store and manipulate groups of objects.
Collection framework provides interfaces like List, Set, and Map for storing and manipulating groups of objects.
It includes classes like ArrayList, LinkedList, HashSet, and HashMap that implement these interfaces.
Collections in Java provide methods for adding, removing, and accessing elements in ...
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, known as a class.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing direct access and manipulation.
Encapsulation also helps in achieving data abstraction, where the internal details of an object are hidden and only the nec...
Yes, we can use try block without catch block to handle exceptions using finally block.
Try block can be used without catch block if there is a finally block to handle exceptions.
Finally block is executed whether an exception is thrown or not.
Example: try { // code that may throw exception } finally { // code to be executed regardless of exception }
I applied via Campus Placement and was interviewed in Jul 2022. There were 2 interview rounds.
This was just a technical test in which there were 30 MCQs based on your job domain. In my case it was questions based on core Java and advanced java and Java Frameworks.
A collection is a framework that provides an architecture to store and manipulate a group of objects.
Collections are used to store, retrieve, manipulate, and communicate data between objects.
They provide various data structures like lists, sets, and maps.
Collections offer methods to add, remove, and search for elements in the collection.
Examples of collections in Java include ArrayList, HashSet, and HashMap.
Thread in Java is a lightweight sub-process that executes a set of instructions independently.
Thread can be defined by extending the Thread class or implementing the Runnable interface.
Thread class provides various methods to control the execution of threads like start(), sleep(), join(), etc.
Runnable interface has only one method run() which needs to be implemented.
Threads can be created and started using the start() ...
Servlets and JSP are Java technologies used for web development.
Servlets are Java classes that handle HTTP requests and responses.
JSP (JavaServer Pages) are HTML pages with embedded Java code.
Servlets and JSP work together to create dynamic web pages.
Servlets are faster than JSP as they directly generate HTML.
JSP is easier to use for web designers as it allows them to focus on HTML and CSS.
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It can be achieved through method overloading and method overriding.
Example: A parent class Animal can have child classes like Dog, Cat, and Cow. All these child classes can have their own implementation of the method 'makeSound', but they can be called using the...

Checked exceptions are checked at compile-time while unchecked exceptions are not checked at compile-time.
Checked exceptions are those which are checked at compile-time and the programmer is forced to handle them using try-catch or throws keyword.
Unchecked exceptions are those which are not checked at compile-time and the programmer is not forced to handle them.
Examples of checked exceptions are IOException, ClassNotFo...
throw is used to explicitly throw an exception while throws is used to declare the exception that a method may throw.
throw is used to handle exceptional situations in the code
throws is used to declare the exceptions that a method may throw
throw is followed by an instance of an exception class

OOPS stands for Object-Oriented Programming System in Java.
OOPS is a programming paradigm that uses objects to represent real-world entities.
It focuses on encapsulation, inheritance, and polymorphism.
Encapsulation is the process of hiding data and methods within a class.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms or behaviors.
Ex...

To find the middle of a linked list in one iteration, use two pointers with different speeds.
Initialize two pointers, one slow and one fast, both pointing to the head of the linked list.
Move the slow pointer one step at a time and the fast pointer two steps at a time.
When the fast pointer reaches the end of the linked list, the slow pointer will be at the middle node.
A binary tree is a data structure consisting of nodes, where each node has at most two children.
Binary tree is used to represent hierarchical relationships between nodes
Traversal of binary tree can be done in three ways: inorder, preorder, postorder
Binary search tree is a type of binary tree where left child is smaller and right child is greater than parent
Balanced binary tree has height difference of at most 1 between...

React components go through various stages in their life cycle, from initialization to destruction.
Initialization: Component is created and initialized with default props and state.
Mounting: Component is rendered on the DOM for the first time.
Updating: Component re-renders when props or state change.
Unmounting: Component is removed from the DOM.
Examples: componentDidMount() for mounting, componentDidUpdate() for updati

OS stands for Operating System. It is a software that manages computer hardware and provides services for computer programs.
OS is the software that acts as an intermediary between computer hardware and user applications.
It manages computer resources such as memory, processors, devices, and file systems.
Examples of popular operating systems include Windows, macOS, Linux, and Android.
Deadlock can be avoided by implementing proper resource allocation strategies and using techniques like deadlock prevention, avoidance, detection, and recovery.
Implement proper resource allocation strategies such as resource ordering, wait-die, wound-wait, etc.
Use techniques like deadlock prevention by ensuring that the system never enters a deadlock state, avoidance by ensuring that the system does not enter an unsafe...
