ADO.NET difference faqs compiled- 1
The document discusses several differences between ADO.NET concepts including:
1) DataReader allows reading one record at a time in a forward-only manner while DataAdapter allows navigating records and updating data in a disconnected manner.
2) DataSet allows caching and manipulating disconnected data across multiple tables while DataReader requires an open connection and only retrieves data from a single query.
3) DataSet.Copy() copies both structure and data of a DataSet while DataSet.Clone() only copies the structure without any data.
4) ADO.NET uses XML, disconnected architecture, and the DataSet object while classic ADO uses binary format, requires active connections, and the Recordset object.

java_vyshali.pdf
This document discusses inheritance in object-oriented programming. Inheritance allows classes to inherit features from other classes, called parent or super classes. The class that inherits is the child, derived, or subclass. Java uses the "extends" keyword for a subclass to inherit from a superclass. Inheritance provides benefits like code reusability, increased reliability, and consistent interfaces. The main types of inheritance discussed are single, multilevel, hierarchical, multiple and hybrid inheritance. The advantages of inheritance include minimizing duplicate code, flexibility, and overriding methods, while disadvantages include slower function calls and increased coupling between classes.

SAD04 - Inheritance
This document discusses object inheritance in systems analysis and design. It covers key concepts like inheritance, composition, aggregation, and the relationships between classes. It explains how inheritance allows classes to inherit attributes and behaviors from parent classes, and how child classes can specialize or extend parent classes through overriding and adding new functionality. The document also discusses the differences between single and multiple inheritance and how inheritance is implemented in languages like Java and .NET.
Inheritance and Substitution
Inheritance allows a child class to inherit attributes and behaviors from a parent class. There are different forms of inheritance like specialization, where the child class is a specialized subtype of the parent, and specification inheritance where the parent class specifies behaviors implemented in the child class. Inheritance provides benefits like code reuse and reliability but also costs like increased complexity and slower execution speed.

4th_class.pdf
Inheritance in Java allows one class to acquire properties and behaviors of another class. This allows code reusability and method overriding to achieve runtime polymorphism. There are three types of inheritance: single, multilevel, and hierarchical. Access modifiers like private, default, protected, and public control the scope and accessibility of classes, methods, and fields. Method overriding provides a specific implementation of a method defined in the parent class.
Introduction to Inheritance in Java for presentation
Inheritance is a key concept in object-oriented programming that allows a class to inherit properties and behavior from another class, known as the parent class. This enables code reusability and promotes a hierarchical structure. In Java, single inheritance allows a class to inherit from one parent class, while interfaces allow for multiple inheritance by implementing multiple interfaces without issues of ambiguity. Inheritance supports polymorphism and building robust software solutions.

Lecture 10
Object oriented programming allows classes to inherit commonly used state and behavior from other classes through inheritance. Inheritance establishes a parent-child relationship between classes where the child inherits members from the parent. Java uses the keyword "extends" for inheritance and does not support multiple inheritance. Abstract classes and interfaces are designed to be inherited only, with abstract classes able to contain implemented methods and interfaces consisting solely of abstract methods that must be implemented in subclasses. Nested, inner, and anonymous classes can be defined within other classes, with inner classes having access to enclosing class members and anonymous classes declared without a name at instantiation.
04 inheritance
This document provides an overview of inheritance in Java. It discusses how inheritance allows code reuse by extending existing classes and creating subclass hierarchies. Inheritance supports polymorphism by allowing subclasses to override methods while still being treated as their parent type. The document uses examples like an Employee class hierarchy to illustrate inheritance concepts and how inheritance enables writing code that can handle various object types without knowing their specific class.

Difference between wcf and asp.net web api
WCF is Microsoft's unified programming model for building service-oriented applications that supports multiple transport protocols and message exchange patterns. It enables building secure and reliable services that can integrate across platforms. ASP.NET Web API is a framework for building HTTP services and is optimized for browser and mobile access. It only supports HTTP protocol but provides MVC features like routing and controllers. WCF supports advanced protocols like reliable messaging while ASP.NET Web API is best for resource-oriented HTTP services that need to support a broad range of clients. The document compares key differences between WCF and ASP.NET Web API across areas like protocols, hosting, description, and when to choose each technology.
Difference between ActionResult() and ViewResult()
ActionResult() is an abstract base class that defines the general result type for MVC actions. ViewResult() is a concrete subclass of ActionResult() that renders a specified view to the response stream. Some key subtypes of ActionResult() include ViewResult(), PartialViewResult(), EmptyResult(), RedirectResult(), and JsonResult(). ActionResult() allows for polymorphism and dynamic behavior by returning different result types from an action. It should be used as the return type when an action may have different behaviors, while ViewResult() can be used when an action will definitely return a view.

Difference between asp.net web api and asp.net mvc
The document compares ASP.NET Web API and ASP.NET MVC. ASP.NET Web API is focused on outputting raw data through HTTP services, while ASP.NET MVC is focused on outputting HTML views. Some key differences include: ASP.NET Web API assumes data comes from the query string or form body, while MVC assumes multiple sources; Web API supports content negotiation and self-hosting, while MVC does not; and Web API is better for non-browser clients while MVC is optimized for browsers. Both can be used together in a single project.
Difference between asp.net web forms and asp.net mvc
The document compares ASP.NET WebForms and ASP.NET MVC across 14 criteria. Some key differences include:
- ASP.NET WebForms uses a "Page Controller" pattern where each page has a code-behind class controller, while ASP.NET MVC uses a "Front Controller" pattern with a single central controller.
- ASP.NET WebForms is tightly coupled with the controller dependent on the view, while ASP.NET MVC is loosely coupled with separate and independent controller and view.
- This loose coupling makes ASP.NET MVC easier to test through test-driven development compared to WebForms.
- ASP.NET MVC gives developers full control over HTML, JavaScript and

Silverlight is a Microsoft plugin that allows developers to use .NET languages to create rich multimedia applications for the web. While AJAX relies mainly on JavaScript and XMLHttpRequest, Silverlight relies on the .NET framework. AJAX supports cross-platform development while Silverlight only supports Windows, Linux with Moonlight, and Mac OS.
Difference between is and as operators in c#
The is operator checks if an object is compatible with a given type and returns a boolean, while the as operator performs reference conversions and returns the object or null. The is operator only considers reference, boxing and unboxing conversions, while the as operator can perform reference conversions. The is operator will never throw exceptions, while the as operator may return null for incompatible types.

- 1. OOPs Reasoning FAQs-1 S.No Questions Answers 1 Does c# support multiple- No. Multiple inheritance is not possible inheritance ? in .NET. This means it is not possible for one class to inherit from multiple classes. However, a class may implement multiple interfaces. We may also declare objects of different classes in a class. This way, the encapsulated class may be instantiated in other classes. 2 Do events have return type ? Events do not have return type. 3 Can you override private virtual No, we cannot access private methods methods ? in inherited classes. 4 Can you allow class to be Yes, just leave the class public and inherited, but prevent the method make the method sealed. from being over-ridden ? 5 Can we have shared events ? Yes, we can have shared event’s note only shared methods can raise shared events. 6 Can you write a class without Yes, we can, then the class belongs to specifying namespace ? which global namespace which has no name. namespace does it belong to by For commercial products, naturally, we default ? would not want global namespace. 7 Can you prevent a class from Yes.If we define a class as “Sealed” in overriding ? C# and “NotInheritable” in VB.NET we can not inherit the class any further. 8 Are private class-level variables Yes, but they are not accessible. inherited ? Although they are not visible or accessible via the class interface, they are inherited. 9 Can you declare the override No, we can't, the signature of the virtual method static while the original method must remain the same, only the method is non-static? keyword virtual is changed to keyword override. 10 Can a constructors that is No, constructors that are declared declared within a base class, within a base class cannot be inherited inherited by subclasses ? by sub-classes.
