- Q1. A program on recursion.
- Ans.
Recursion is a programming technique where a function calls itself to solve a problem.
Recursion involves a base case and a recursive case
Recursion can be used to solve problems like factorial, Fibonacci sequence, and binary search
Recursion can be less efficient than iterative solutions for some problems
- Q2. Is a string mutable/immutable with an example
- Ans.
A string can be both mutable and immutable depending on the programming language.
In languages like Java and Python, strings are immutable.
In languages like C++ and C#, strings are mutable.
Immutable strings cannot be modified once created, while mutable strings can be modified.
Example of immutable string: 'hello world'.replace('o', '0') returns 'hell0 w0rld'.
Example of mutable string: string s = 'hello'; s[0] = 'j'; s n
- Q3. OOPS concept with examples
- Ans.
OOPS is a programming paradigm based on the concept of objects.
OOPS stands for Object-Oriented Programming System
It focuses on creating objects that contain both data and functions
Encapsulation, Inheritance, and Polymorphism are the three main pillars of OOPS
Example: A car is an object that has properties like color, model, and functions like start, stop, and accelerate

- Q1. String is immutable. Array and arraylist differences
- Ans.
String is immutable, array and arraylist are mutable data structures.
String is immutable, meaning its value cannot be changed once it is created.
Array is a fixed-size data structure that stores elements of the same data type.
ArrayList is a dynamic array that can grow or shrink in size as needed.
Example: String str = "hello"; char[] arr = {'h', 'e', 'l', 'l', 'o'}; ArrayList
list = new ArrayList ();
- Q2. Deadlock scenario in thread
- Ans.
Deadlock scenario in thread occurs when two or more threads are waiting for each other to release resources, causing a standstill.
Two threads each holding a resource needed by the other thread
No thread can proceed until the other releases the resource
Can be avoided by careful resource allocation and ordering
- Q3. Struts architecture
- Q4. Array sort program

Polymorphism: The ability for objects of different classes to respond to the same method call.
Abstraction: Hidi...
- Q3. Explain synchronization.
- Ans.
Synchronization is the coordination of multiple processes or threads to ensure they access shared resources in a controlled manner.
Synchronization is important in multi-threaded programming to prevent race conditions and ensure data consistency.
Common synchronization mechanisms include locks, semaphores, and monitors.
For example, using a mutex lock to protect a critical section of code from being accessed by multiple t
- Q4. Explain Normalization.
- Ans.
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization is used to eliminate data redundancy by breaking up tables into smaller, related tables.
It helps in reducing data anomalies such as update, insert, and delete anomalies.
Normalization is achieved through a series of stages called normal forms, such as 1NF, 2NF, 3NF, and BCNF.
For example, in a datab...

- Ans.
Array is a fixed-size collection of elements of the same data type, while ArrayList is a dynamic-size collection of objects.
Array is a static data structure with a fixed size, while ArrayList is a dynamic data structure that can grow or shrink in size.
