Entity Framework is an ORM tool used to map database tables to classes in .NET applications.

• Entity Framework simplifies database access by allowing developers to work with objects instead of SQL statements.

• It supports various database providers such as SQL Server, MySQL, and Oracle.

• It provides features like LINQ to Entities, automatic change tracking, and database migrations.

• Example: In my last project, I used Entity F...read more

Projects in engineering involve designing, building, and testing systems and structures to solve problems.

• Identify problem and constraints

• Design solution and create blueprints

• Build and test prototype

• Refine design based on testing results

• Implement final solution

• Examples: building a bridge, designing a new software application

String buffer and string builder are classes in Java used for manipulating strings.

• String buffer is a mutable sequence of characters that can be modified without creating a new object.

• String builder is similar to string buffer but is not synchronized, making it faster in single-threaded applications.

• Both classes provide methods for appending, inserting, deleting, and replacing characters in a string.

• Example: StringBuff...read more

Code for palindrome in any language like c c++ or c#

• Take input string from user

• Reverse the string

• Compare original and reversed string

• If same, then it is a palindrome

OOPs concepts are the fundamental principles of object-oriented programming.

• Encapsulation - binding data and functions together

• Inheritance - creating new classes from existing ones

• Polymorphism - ability of objects to take on many forms

• Abstraction - hiding implementation details

• Example: A car is an object that encapsulates data like speed and functions like accelerate and brake

• Example: A child class can inherit properti...read more

Collections in Java are pre-built data structures that allow storing and manipulating groups of objects.

• Collections provide a set of interfaces and classes to work with data structures like lists, sets, maps, etc.

• They offer various methods to add, remove, search, sort, and iterate over elements in the collection.

• Examples of collections include ArrayList, HashSet, TreeMap, etc.

• Collections framework is part of the Java A...read more

Encapsulation is hiding implementation details while abstraction is hiding unnecessary details.

• Encapsulation is achieved through access modifiers like private, protected, and public.

• Abstraction is achieved through abstract classes and interfaces.

• Encapsulation is used to protect data from outside interference.

• Abstraction is used to provide a simplified view of a complex system.

• Example of encapsulation: Getters and sette...read more
