Consider the following code:

public class Example extends Thread
{
public void run()
{
System.out.println ("Hello");
}

public static void main (String args[])
{
new Example();
}
}

Select the correct option regarding the preceding code ?

  
1, The code will not compile.
2, The code will compile but will not execute.
3, The code will compile, execute, and display Hello as the output.
4, The code will compile, execute, but will not display anything.

Answer : 4 (More...)

Consider the following two classes:

public class Example1
{
public static int num;
static
{
num=5;
}
}


public class Example2
{
public static void main(String[] args)
{
System.out.println(Example1.num);
}
}

Select the correct option regarding the preceding classes.?

  
1, The Example2 class will execute without any output.
2, The Example2 class will execute with the following output:5

3, The Example2 class will not compile as it does not calls the constructor of the Example 1 class.
4, The Example2 class will not execute as it does not calls the constructor of the Example 1 class.

Answer : 2 (More...)

Why 'static' keyword is used before Main()?

  
Program execution starts from Main(). S it should be called before the creation of any object. By using static the Main() can now be called directly through the class name and there is no need to create the object to call it. So Main() is declared as static. (More...)

What is public, static and void?

  
public :The keyword public is an access modifier that tells the C# compiler that the Main method is accessible by anyone.

static :The keyword static declares that the Main method is a global one and can be called without creating an instance of the class. The compiler stores the address of the method as the entry point and uses this information to begin execution before any objects are created.

void : The keyword void is a type modifier that states that the Main method does not return any value. (More...)

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 NULL AND VOID pointer?

  
NULL can be value for pointer type variables.
VOID is a type identifier which has not size.
NULL and void are not same. Example: void* ptr = NULL; (More...)

What is the main purpose of having Conversation Group?

  
It's a way of grouping all the dialogs that are used for a particular task. All the dialogs associated with processing a particular order would be grouped into a single conversation group. The conversation group is implemented as a conversation group identifier, which is included with all messages in all dialogs contained in the conversation group. When a message is received from any of the dialogs in a conversation group, the conversation group is locked with a lock that is held by the receiving transaction. For the duration of the transaction, only the thread that holds the lock can receive messages from any of the dialogs in the conversation group. This makes our order entry application much easier to write because even though we use many threads for scalability, any particular order is only processed on one thread at a time. This means we don't have to make our application resilient to problems that are caused by the simultaneous processing of a single order on multiple threads. (More...)

Can I easily rename a solution or project?

  
Yes-right-click from the Solution Explorer and choose Rename.You'll also have to edit the namespace declarations in any source code files you've created. (More...)

Where is image data loaded into ImageList controls actually stored in the project?

  
Each form has an associated resource file (with a .resx extension) where image data and localized strings are stored.You can see this by clicking the Show All Files icon in the Solution Explorer. (More...)

What is the Main Difference between ASP and ASP.NET?

  
ASP Contains Scripts which are not complied where as in asp.net the code is compiled (More...)

What are the main benefits of Office SharePoint Server 2007?

  
Office SharePoint Server 2007 provides a single integrated platform to manage intranet, extranet,and Internet applications across the enterprise.

* Business users gain greater control over the storage, security, distribution, and management of their electronic content, with tools that are easy to use and tightly integrated into familiar,everyday applications.

* Organizations can accelerate shared business processes with customers and partners across organizational boundaries using InfoPath Forms Services-driven solutions.

* Information workers can find information and people efficiently and easily through the-facilitated information-sharing functionality and simplified content publishing. In addition, access to back-end data is achieved easily through a browser, and views into this data can be personalized.

* Administrators have powerful tools at their fingertips that ease deployment, management, and system administration, so they can spend more time on strategic tasks.

* Developers have a rich platform to build a new class of applications, called Office Business Applications, that combine powerful developer functionality with the flexibility and ease of deployment of Office SharePoint Server 2007. Through the use of out-of-the-box application services, developers can build richer applications with less code. (More...)
