Partial is a keyword in C# used to define partial classes, methods, and structures.
Partial classes allow splitting a class definition into multiple files.
Partial methods allow defining a method in one part of the class and implementing it in another part.
Partial structures allow splitting a structure definition into multiple files.
Partial keyword is also used with interfaces and namespaces.
Thread is a lightweight unit of a process that executes instructions concurrently with other threads.
Threads allow for parallel execution of code.
They share the same memory space as the process they belong to.
Thread class is used to create and manage threads.
Thread synchronization is important to avoid race conditions.
Examples of multithreaded applications include web servers and video games.
Synchronous means waiting for a task to complete before moving on, while Asynchronous means not waiting for a task to complete before moving on.
Synchronous operations block the execution of code until the task is completed.
Asynchronous operations allow the code to continue executing while the task is being completed.
Synchronous operations are easier to understand and debug, but can cause performance issues.
Asynchronous...
Enum is a value type that represents a set of named constants in C#.
Enums are used to define a set of named constants that represent a range of values.

Enums can be defined with a specific underlying data type, such as int or byte.
Enums can have associated values and methods.
Example: enum Days { Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sund...
Collection is a group of related objects of the same type that can be accessed and manipulated using methods.
Collections are used to store, retrieve, manipulate, and communicate aggregate data.

Overriding in C# is a feature that allows a derived class to provide a different implementation of a method that is already defined in its base class.
Overriding is used to achieve runtime polymorphism.
The method in the derived class must have the same name, return type, and parameters as the method in the base class.
The 'override' keyword is used to indicate that a method is intended to override a base class method.
The...
A class is a blueprint for creating objects, while an object is an instance of a class.
A class defines the properties and methods of an object
An object is created from a class using the 'new' keyword
Multiple objects can be created from a single class
Objects can interact with each other through their methods and properties
Abstraction is the process of hiding complex implementation details and showing only necessary information.
Abstraction helps in reducing complexity and increasing efficiency.
It allows us to focus on what is important and ignore what is not.
For example, a car dashboard is an abstraction as it shows only necessary information like speed, fuel level, etc. and hides the complex workings of the car.
Abstraction can be achiev...

Java is a class-based OOPs language
Encapsulation, Inheritance, Polymorphism, and Abstraction are the four pillars of OOPs
Objects have state and behavior
Java supports interfaces, which allow for multiple inheritance

Java solves machine dependency by using bytecode and virtual machine.
Java code is compiled into bytecode which is platform-independent
The bytecode is executed by the Java Virtual Machine (JVM) which is platform-specific
JVM translates bytecode into machine code for the specific platform
This allows Java code to run on any platform with a JVM installed
Example: A Java program compiled on Windows can run on Linux or Mac as
