What is the difference between Object and Instance?

Posted By :Narayanan     Posted Date :February 28, 2013    Points :40   Category :OOPS 
An instance of a user-defined type is called an object. We can instantiate many objects from one class.
An object is an instance of a class.

Difference between type constructor and instance constructor? What is static constructor, when it will be fired? And what is its use?

  
(Class constructor method is also known as type constructor or type initializer)
Instance constructor is executed when a new instance of type is created and the class constructor is executed after the type is loaded and before any one of the type members is accessed. (It will get executed only 1st time, when we call any static methods/fields in the same class.) Class constructors are used for static field initialization. Only one class constructor per type is permitted, and it cannot use the vararg (variable argument) calling convention. (More...)

what is the difference between object based and object oriented programming language?

  
object based language such as VB 6.0. The main difference is about the pureness of OO nature.VB 6.0 does not handle each and every thing as an object VB.NET or C# or Java does so (More...)

Difference between Object Base and Object Oriented ?

  
In object oriented you use build in class, template class and also define your own class but in object base we can only use build in class User cannot create his own class.
Thats all. (More...)

What is a SPSite and SPWeb object, and what is the difference between each of the objects?

  
The SPSite object represents a collection of sites (site collection [a top level site and all its subsites]). The SPWeb object represents an instance SharePoint Web, and SPWeb object contains things like the actual content. A SPSite object contains the various subsites and the information regarding them.
(More...)

Difference between a java object reference and c++ pointer.

  
The prime difference is that pointers are to locate the address of the primitive variables only, where as object reference locates the object in the heap. (More...)

Difference between Cache object and application object ?

  
Difference between the Cache and Application objects is that the Cache object provides cache-specific features, such as dependencies and expiration policies. (More...)

Explain the difference between cache object and application object.

  
Application Object: Application variable/object stores an Object with a scope of availability of the entire Application unless explicitly destroyed.

Caching Object: The lifetime of cache is throughout the lifetime of an application or is based upon timeouts (More...)

What is the difference between static and instance methods

  
A method declared with a static modifier is a static method. A static method does not operate on a specific instance and can only access static members.

A method declared without a static modifier is an instance method. An instance method operates on a specific instance and can access both static and instance members. The instance on which an instance method was invoked can be explicitly accessed as this. It is an error to refer to this in a static method.
(More...)

What is the difference between class and object?

  
Classes describe the structure of objects, while objects are usable instances of classes. Each instance is an exact yet distinct copy of its class. Because an object is an instance of a class, the act of creating an object is called instantiation.
Usually, changing the data in one object does not change the data in any other object. (More...)

Difference Between Delete and Truncate

  
.Delete table is a logged operation, so the deletion of each row gets logged in the transaction log, which makes it slow.

. Truncate table also deletes all the rows in a table, but it won't log the deletion of each row, instead it logs the de-allocation of the data pages of the table, which makes it faster. Of course, truncate table cannot be rolled back.

. Truncate table is functionally identical to delete statement with no "where clause" both remove all rows in the table. But truncate table is faster and uses fewer system and transaction log resources than delete.

. Truncate table removes all rows from a table, but the table structure and its columns, constraints, indexes etc., remains as it is.

. In truncate table the counter used by an identity column for new rows is reset to the seed for the column.

. If you want to retain the identity counter, use delete statement instead.

. If you want to remove table definition and its data, use the drop table statement.

. You cannot use truncate table on a table referenced by a foreign key constraint; instead, use delete statement without a where clause. Because truncate table is not logged, it cannot activate a trigger.

. Truncate table may not be used on tables participating in an indexed view. (More...)

Difference between assembly manifest & metadata?

  
assembly manifest - An integral part of every assembly that renders the assembly self-describing. The assembly manifest contains the assembly's metadata. The manifest establishes the assembly identity, specifies the files that make up the assembly implementation, specifies the types and resources that make up the assembly, itemizes the compile-time dependencies on other assemblies, and specifies the set of permissions required for the assembly to run properly. This information is used at run time to resolve references, enforce version binding policy, and validate the integrity of loaded assemblies. The self-describing nature of assemblies also helps makes zero-impact install and XCOPY deployment feasible.

metadata - Information that describes every element managed by the common language runtime: an assembly, loadable file, type, method, and so on. This can include information required for debugging and garbage collection, as well as security attributes, marshaling data, extended class and member definitions, version binding, and other information required by the runtime. (More...)

What is the difference between ref & out parameters?

  
An argument passed to a ref parameter must first be initialized. Compare this to an out parameter, whose argument does not have to be explicitly initialized before being passed to an out parameter. (More...)

What is the difference between a Struct and a Class?

  
The struct type is suitable for representing lightweight objects such as Point, Rectangle, and Color. Although it is possible to represent a point as a class, a struct is more efficient in some scenarios. For example, if you declare an array of 1000 Point objects, you will allocate additional memory for referencing each object. In this case, the struct is less expensive.

When you create a struct object using the new operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the new operator. If you do not use new, the fields will remain unassigned and the object cannot be used until all of the fields are initialized.

It is an error to declare a default (parameterless) constructor for a struct. A default constructor is always provided to initialize the struct members to their default values.

It is an error to initialize an instance field in a struct.

There is no inheritance for structs as there is for classes. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Structs, however, inherit from the base class Object. A struct can implement interfaces, and it does that exactly as classes do.

A struct is a value type, while a class is a reference type. (More...)
