OOPs concepts are fundamental principles of object-oriented programming that help in creating modular and reusable code.
Encapsulation helps in hiding the implementation details of an object and provides a clean interface for interacting with it.
Inheritance allows creating new classes based on existing ones, reducing code duplication and promoting code reuse.
Polymorphism enables objects to take on multiple forms, allowi...
Activity refers to a single screen with a user interface. Binding is a way to connect data to the UI elements.
Activity is a component of an Android app that represents a single screen with a user interface.
Binding is a way to connect data to the UI elements in an Activity.
Data binding can be done using XML or programmatically.
Binding can be used to update the UI automatically when the data changes.
Services are modular, reusable components that perform specific tasks and can be accessed by other parts of an application.
Services are used to separate business logic from the UI layer.
They can be used to perform tasks such as data retrieval, validation, and manipulation.
Services can be shared across multiple components and modules.
Examples include HTTP services for making API calls, authentication services, and loggi
Recyclerview is a view group that displays a list of scrollable items and reuses views as they scroll off the screen.
Recyclerview is a more flexible and efficient version of ListView and GridView.
It uses a LayoutManager to arrange items in a list or grid format.
It also uses an Adapter to provide data to the views and recycle views as they scroll off the screen.
Recyclerview can also support animations and item decoratio...
Data can be fetched using APIs and passed to the view using templating engines or front-end frameworks.
Use AJAX calls to fetch data from the backend APIs
Parse the data received in JSON format
Use templating engines like Handlebars or front-end frameworks like React to pass the data to the view
Render the data dynamically on the view
MVVM, MVC, and MVP are design patterns used in software development to separate concerns and improve code maintainability.
MVC stands for Model-View-Controller and separates the application into three interconnected components. The model represents the data and business logic, the view displays the data to the user, and the controller handles user input and updates the model and view accordingly.
MVP stands for Model-Vie...

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 motor consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part.
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...
A program to generate a geometric progression (GP).
Take the first term, common ratio and number of terms as input.
Use a loop to calculate each term of the GP.
Print the generated GP as output.
A program to print factorial using recursion
Define a function to calculate factorial recursively
Base case: if the number is 0 or 1, return 1
Recursive case: multiply the number with factorial of (number - 1)
Print the factorial of a given number
