Interface defines a contract while abstract class provides partial implementation.
Interfaces can only have abstract methods while abstract classes can have both abstract and non-abstract methods.
A class can implement multiple interfaces but can only inherit from one abstract class.
Interfaces are used for loose coupling while abstract classes are used for code reusability.
Example of interface: Runnable interface in Java...
Method overloading is when a class has multiple methods with the same name but different parameters.
Method overloading allows for flexibility in method calls
The methods must have different parameters, such as different data types or different numbers of parameters
Example: public void print(int num) and public void print(String str)
The compiler determines which method to call based on the arguments passed
Indexing in SQL Server database
Indexing improves query performance by creating a structure that allows for faster data retrieval
Clustered and non-clustered indexes are the two types of indexes in SQL Server
Clustered indexes determine the physical order of data in a table while non-clustered indexes create a separate structure
Indexing should be done strategically to avoid over-indexing which can slow down data modificat

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed
A program to print all prime numbers
Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.
