Q1. Pillars of Object Oriented Programming. Real Life Example of Pillars of OOPS.
Ans. 
Pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism. Real life example: Vehicles.
• Inheritance: Car and Bike classes inheriting from Vehicle class.

• Encapsulation: Data hiding in a class to protect it from outside interference.

• Abstraction: Using a remote control to operate a TV without knowing its internal workings.

• Polymorphism: Overloading a method with different parameters in a class.

Q2. Is Function Overloading the Only Example of Compile Time Polymorphism ?
Ans. 
No, Function Overloading is not the only example of Compile Time Polymorphism.
• Function Templates are another example of Compile Time Polymorphism where a single function can operate on different data types.

• Operator Overloading is also an example of Compile Time Polymorphism where operators can be overloaded to work with different data types.

• Static Polymorphism achieved through method overloading is another example of C

Q3. Difference Between Arrays and LinkedLists. Cons and Pros of Using Them. Which Out of Both Would be Preferable in Different Situations ?
Ans. 
Arrays store elements in contiguous memory locations, while LinkedLists store elements in nodes with pointers to the next element.
• Arrays have constant time access to elements using index, while LinkedLists have O(n) access time as they need to traverse from the beginning.

• Arrays have fixed size, while LinkedLists can dynamically grow and shrink in size.

• Arrays are better for random access and search operations, while Lin...read more

Q4. Creating LinkedList Class , Insertion and Deletion in a LinkedList , Reversing and Sorting a LinkedList , Questions on Circular Linked List.
Ans. 
Answering questions related to LinkedList operations and Circular LinkedList.
• LinkedList Class: Implement a class with nodes containing data and a reference to the next node.

• Insertion: Add a new node at the beginning, end, or at a specific position in the LinkedList.

• Deletion: Remove a node by updating references to skip over it.

• Reversing: Traverse the LinkedList and reverse the links between nodes.

• Sorting: Implement a s...read more

Q6. Reverse a String without Using Any Loop or Using Any Other Data Structure.
Ans. 
Use recursion to reverse the string without using loops or other data structures.
• Create a recursive function that takes the string as input.

• In the function, check if the string is empty or has only one character, return the string in that case.

• Otherwise, call the function recursively with the substring excluding the first character and concatenate the first character at the end.

Q7. Program to Find the Maximum Occurring Number in an Array. Which Data Structure can be Used for Making the Code More Efficient ?
Ans. 
Use a hashmap to store frequency of each number in the array for efficient retrieval of maximum occurring number.
• Use a hashmap to store the frequency of each number in the array.

• Iterate through the array and update the frequency count in the hashmap.

• Find the number with the highest frequency in the hashmap to get the maximum occurring number.

Q8. What is Multi-Threading in Java ? What are Generics ?
Ans. 
Multi-Threading in Java allows multiple threads to execute concurrently. Generics in Java enable type-safe collections and classes.
• Multi-Threading in Java allows for concurrent execution of multiple threads.

• Generics in Java enable type-safe collections and classes by allowing the use of parameterized types.

• Example of Multi-Threading: creating a new thread using the Thread class and implementing the run() method.

• Example...read more

Q1. Explain 4 pillars of OOP.
Ans. 
The 4 pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction.
• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Inheritance: Allowing a class to inherit properties and behavior from another class.

• Polymorphism: The ability for objects to be treated as instances of their parent class.

• Abstraction: Hiding the complex implementation details and showing only the necessa
