Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.
OOP focuses on creating objects that interact with each other to solve problems
Encapsulation, inheritance, and polymorphism are key principles of OOP
Examples of OOP languages include Java, C++, and Python
Multi threading is a programming concept where multiple threads within a process execute independently to improve performance.
Allows for concurrent execution of tasks within a single process
Improves performance by utilizing multiple CPU cores
Requires careful synchronization to avoid race conditions
Examples include web servers handling multiple requests simultaneously
Java is not 100% OOP because it supports primitive data types and static methods.
Java has primitive data types like int, double, etc. which are not objects.
Java allows static methods which do not require an instance of a class to be called.
Java also has the concept of wrapper classes to convert primitive data types to objects.
Collections in Java are classes and interfaces that provide a way to store and manipulate groups of objects.
Collections provide dynamic data structures like List, Set, and Map.
They offer methods to add, remove, and manipulate elements in the collection.
Examples include ArrayList, LinkedList, HashSet, and HashMap.
A hash map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash map uses a hash function to determine the index of the key-value pair in the underlying array.
Collision resolution techniques like chaining or open addressing are used to handle situations where multiple keys hash to the same index.
Hash maps typically have O(1) average time complexity for i...

OOPs concept in JAVA refers to Object-Oriented Programming principles like encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit (object).
Inheritance: Allows a class to inherit properties and behavior from another class.
Polymorphism: Ability of a method to do different things based on the object it is acting upon.
Abstraction: Hidin...
Memory management in JAVA involves allocation, usage, and deallocation of memory for objects and variables.
Java uses automatic memory management through garbage collection
Memory is allocated on the heap for objects and on the stack for local variables
Java Virtual Machine (JVM) manages memory allocation and deallocation
Memory leaks can occur if objects are not properly dereferenced
Reflection in Java allows programs to inspect or modify their own structure at runtime.
Reflection allows access to class information, fields, methods, and constructors at runtime.
It is commonly used in frameworks like Spring and Hibernate for dependency injection and ORM.
Example: Using reflection to dynamically load classes or invoke methods based on user input.

I applied via Recruitment Consulltant and was interviewed in Aug 2023. There were 2 interview rounds.
Good and tricky questions
OOPs concepts in Java are fundamental principles of object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class. Example: Car class inheriting from Vehicle class.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Using private variables and public methods in ...
Java is platform independent because of its 'write once, run anywhere' principle.
Java programs are compiled into bytecode which can run on any Java Virtual Machine (JVM) regardless of the underlying platform.
This allows Java programs to be executed on different operating systems without any modifications.
Examples of platform independent Java applications include web applications, mobile apps, and enterprise software.
Abstract classes can have both abstract and non-abstract methods, while interfaces can only have abstract methods.
Abstract classes can have constructors, fields, and non-abstract methods, while interfaces cannot.
A class can only extend one abstract class, but it can implement multiple interfaces.
Abstract classes are used to define common characteristics of subclasses, while interfaces are used to define contracts for c...
