Access modifiers determine the visibility and accessibility of classes, methods, and variables in object-oriented programming.
Access modifiers are keywords used in programming languages like Java, C++, and C#.
They control the visibility and accessibility of classes, methods, and variables.

A prime number is a number greater than 1 that is divisible only by 1 and itself.
Start with a number greater than 1
Check if the number is divisible by any number from 2 to its square root
If it is divisible by any number, it is not prime
If it is not divisible by any number, it is prime
Call by value passes a copy of the value, while call by reference passes a reference to the original value.
Call by value creates a new copy of the value, so changes made inside the function do not affect the original value.
Call by reference passes a reference to the original value, so changes made inside the function affect the original value.
In call by value, the function works with a local copy of the variable.
In cal...
Structure refers to the arrangement or organization of elements in a system or program.

Encapsulation: Bundling data and methods together in a class.
Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.
Polymorphism: Ability of objects to take on many forms, allowing methods to be overridden.
Abstraction: Hiding complex implementation details and providing simplified interfaces.

They provide a way to efficiently access and manipulate the stored data.
Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.
External CSS and JS files can be linked to HTML using the and
CSS is used to style and format HTML web pages, making them visually appealing and user-friendly.
CSS allows for separation of style and content, making it easier to maintain and update web pages.
It provides a wide range of styling options, such as changing colors, fonts, layouts, and animations.
CSS enables responsive design, allowing web pages to adapt to different screen sizes and devices.
It improves accessibility by ...
The Observer design pattern defines a one-to-many dependency between objects, so that when one object changes state, all its dependents are notified and updated automatically.
The Observer pattern is used to establish communication between objects in a loosely coupled manner.
It allows multiple observers (dependents) to be notified when the state of a subject (observable) changes.
The subject maintains a list of observers...
An algorithm is a step-by-step procedure or set of rules for solving a problem or accomplishing a task.
An algorithm is a well-defined computational procedure.
It consists of a sequence of instructions that are executed in a specific order.
Algorithms can be represented using pseudocode, flowcharts, or programming languages.
They are used in various fields like computer science, mathematics, and engineering.
Examples of alg...

I am constantly learning and improving my Java skills.
I applied via Approached by Company and was interviewed in Nov 2022. There were 2 interview rounds.
Inheritance is a mechanism in OOP where a new class is derived from an existing class.
It allows the new class to inherit the properties and methods of the existing class.
The existing class is called the superclass or parent class, while the new class is called the subclass or child class.
The subclass can add new properties and methods or override the existing ones.
It promotes code reuse and makes the code more organize...

Constructors are used to initialize objects in Java.
Constructors are special methods that have the same name as the class.
They are used to allocate memory for an object and initialize its state.
Constructors can have parameters to initialize object properties.
They are called automatically when an object is created using the 'new' keyword.
Constructors can be overloaded to create objects with different initial states.
An interface in Java is a blueprint of a class that defines a set of methods without implementation.
An interface can have abstract methods, default methods, and static methods.
It is used to achieve abstraction and multiple inheritance in Java.
Classes implement interfaces using the 'implements' keyword.
Interfaces can be used to create loosely coupled systems and promote code reusability.
Example: 'Comparable' interface i...
Extend is used to inherit properties and methods from a class, while implement is used to implement interfaces.
Extend is used to create a subclass that inherits properties and methods from a superclass.
Implement is used to define a class that implements the methods declared in an interface.
A class can extend only one superclass, but it can implement multiple interfaces.
Extend is used for inheritance, while implement is

Motors are rated in KW because they consume power, while transformers and generators are rated in KVA because they produce power.
Motors convert electrical energy into mechanical energy, so they consume power and are rated in KW.
Transformers and generators produce electrical energy, so they are rated in KVA based on their apparent power.
KVA takes into account both the real power (KW) and the reactive power (KVAR) produc...
The type of motor used in ceiling fans is an induction motor.
Ceiling fans typically use single-phase induction motors.
These motors are designed to provide a constant speed and are efficient in converting electrical energy into mechanical energy.

The stator contains windings that create a rotating m...
A thermal power plant generates electricity by converting heat energy into mechanical energy.
Thermal power plants use fossil fuels or nuclear energy to heat water and produce steam.
The steam drives a turbine, which is connected to a generator that produces electricity.
The heat source can be coal, natural gas, oil, or nuclear reactions.
The steam is condensed back into water and recycled in a closed-loop system.
Thermal p...
