- Q1. Differenece between Stack and heap
- Ans.
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 = ...
- Q2. Oops with real world example
- Ans.
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

- Q1. DSA CIRCULAR QUEUE
- Q2. POLYMORPHISM and its types
- Ans.
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...

- Q2. What is Object-oriented programming?
- Ans.
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
- Q3. What is encapsulation?
- Ans.
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 ...
- Q4. Program to find prime number
- Ans.
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

- Q1. Basic questions of java like core java , oops concepts
- Q2. What is constructor
- Ans.
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 } }
- Q3. How can we achieve multiple inheritance in java
- Ans.
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

4 Questions
- Q1. Tell me about your technical skills and background?
- Q2. What is the use of pointers?
- Ans.
Pointers are variables that store memory addresses. They are used to manipulate data structures and improve program efficiency.
Pointers allow for dynamic memory allocation
Pointers can be used to pass values by reference
Pointers can be used to create linked lists
Pointers can be used to access array elements
Example: int *ptr = # // stores address of num variable
Example: void swap(int *x, int *y) { int temp = *x; *x =...
- Q3. Difference between arrays and linkedlist?
- Ans.
Arrays are fixed in size and contiguous memory while linked lists are dynamic and non-contiguous.
Arrays have constant time access to elements while linked lists require traversal.
Arrays are better for random access while linked lists are better for insertion and deletion.
Arrays use less memory overhead than linked lists.
Example: Array of strings - ['apple', 'banana', 'orange']
- Q4. Tell me about variables and its types?
- Ans.
Variables are containers that store data values. There are different types of variables in programming.
Variables are declared using keywords like var, let, const.
Variables can store different types of data such as numbers, strings, booleans, objects, arrays, etc.
Variables can be global or local depending on where they are declared.
Variables can be reassigned with new values.
Examples: var age = 25; let name = 'John'; co
