Coding and SQL quries
Stack is used for static memory allocation and stores local variables, while heap is used for dynamic memory allocation and stores objects.
Stack memory is allocated in a contiguous block and is faster to access.
Heap memory is allocated in a non-contiguous manner and is slower to access.
Stack memory is automatically managed by the system, while heap memory needs to be manually managed by the programmer.
Example: int x = ...
Oops is a programming paradigm that focuses on objects and classes. Real world example: Car
Oops focuses on objects and classes
Objects have attributes (variables) and behaviors (methods)
Example: Car - attributes like color, model, speed; behaviors like drive, stop
Polymorphism is the ability of a single function or method to operate on different data types.
Types of polymorphism: compile-time (method overloading) and runtime (method overriding)
Compile-time polymorphism: multiple methods with the same name but different parameters
Runtime polymorphism: a subclass provides a specific implementation of a method that is already provided by its parent class
Example of compile-time polym...

Object-oriented programming is a programming paradigm that organizes code into objects that interact with each other.
Encourages modular and reusable code
Focuses on data and behavior encapsulation
Supports inheritance and polymorphism
Examples: Java, C++, Python
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation is a fundamental principle of object-oriented programming.
It helps in achieving data abstraction and data hiding.
By encapsulating data and methods within a class, we can control access to them.
Encapsulation improves code maintainability and reusability.
Example: A class with private ...
Program to find prime number
A prime number is a number greater than 1 that has no positive divisors other than 1 and itself
To check if a number is prime, iterate from 2 to the square root of the number and check if it divides the number evenly
If the number is divisible by any number in the range, it is not prime
Optimization: Only iterate up to the square root of the number, as factors repeat after that
I applied via Company Website and was interviewed before Apr 2023. There were 2 interview rounds.
I applied via Campus Placement
A constructor is a special method that is used to initialize objects of a class.
Constructors have the same name as the class they belong to.
They are called automatically when an object is created.
They can be used to set initial values for object properties.
Constructors can be overloaded to accept different parameters.
Example: public class Car { public Car() { // constructor code here } }
Multiple inheritance cannot be achieved directly in Java, but it can be simulated using interfaces or abstract classes.
Java does not support multiple inheritance of classes
Multiple inheritance can be achieved using interfaces or abstract classes
Interfaces allow a class to inherit from multiple interfaces
Abstract classes can provide partial implementation and can be extended by a single class
