OOP stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOP focuses on creating objects that contain data and methods to manipulate that data.
Encapsulation: Objects hide their internal state and require interaction through defined interfaces.

Dispose and finalize are methods used for releasing resources in .NET.
Dispose is used to release unmanaged resources immediately.
Finalize is used to release managed resources when the garbage collector runs.
Dispose can be called manually or through the using statement.
Finalize is called automatically by the garbage collector.

- Q2. Explain oops concepts?
- Ans.
OOPs concepts are the principles of Object-Oriented Programming that help in designing and implementing software solutions.
Encapsulation - binding data and functions together
Inheritance - creating new classes from existing ones
Polymorphism - ability of objects to take on multiple forms
Abstraction - hiding implementation details
Objects - instances of classes that encapsulate data and behavior
- Q3. What is inheritance and disadavantages of it?
- Ans.
Inheritance is a mechanism in OOP where a new class is derived from an existing class.
It allows for code reusability and promotes a hierarchical structure.
It can lead to tight coupling and make the code harder to maintain.
It can also result in the creation of unnecessary classes and increase complexity.
Example: A Car class can inherit properties and methods from a Vehicle class.
Example: A Square class can inherit prope
- Q4. Explicite interface?
- Ans.
Explicit interface is a way to implement multiple interfaces with same method names.
Explicit interface is used to avoid naming conflicts when implementing multiple interfaces.
It is implemented by prefixing the interface name to the method name.
It is useful when implementing COM interfaces in .NET.
Example: void IInterface1.Method() and void IInterface2.Method()
- Q5. Interface vs abstract classes
- Ans.
Interface defines only method signatures while abstract class can have method implementations.
Interfaces can be implemented by multiple classes while abstract classes can only be extended by one class.
Interfaces are used for achieving multiple inheritance in Java while abstract classes are used for single inheritance.
Interfaces cannot have constructors while abstract classes can have constructors.
An example of an inter...
- Q6. Startup method in .net core?
- Ans.
Startup method in .NET Core is used to configure the application's services and middleware.
Startup method is defined in Startup.cs file.
It includes ConfigureServices and Configure methods.
ConfigureServices is used to add services to the dependency injection container.
Configure is used to configure the HTTP request pipeline.
Example: public void ConfigureServices(IServiceCollection services) { services.AddMvc(); }
Example...
- Q7. What are Http verbs?
- Ans.
HTTP verbs are used to indicate the type of action being performed on a resource.
HTTP verbs include GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS
GET is used to retrieve data from a server
POST is used to submit data to a server
PUT is used to update an existing resource on a server
DELETE is used to delete a resource from a server
PATCH is used to partially update a resource on a server
HEAD is used to retrieve only the head...

Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
- Q2. Uses of interface, inheritance
- Ans.
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i
- Q3. SQL query for join of tables
- Ans.
SQL query for joining tables
Use JOIN keyword to combine two or more tables based on a related column
Specify the columns to be selected using SELECT keyword

- Q4. Java concepts used in your project
- Ans.
Used Java concepts such as inheritance, polymorphism, and exception handling in my project.
Implemented inheritance to create a base class and derived classes with specific functionalities.
Utilized polymorphism to allow objects of different classes to be treated as if they were of the same class.
Implemented exception handling to handle errors and prevent program crashes.
Used interfaces to define a set of methods that a ...
- Q5. Overloading vs overriding, practical uses
- Ans.
Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as a method in the superclass.
Overloading is used to provide different ways to call a method with different parameters
Overriding is used to provide a specific implementation of a method in a subclass
Overloading is resolved at compile-time while overriding is r...
