what is different between BCL (Base Class Library) and FCL (Framework Class Library) in Microsoft dot net (.net)?

Base Class Library :

The Base Class Library (BCL) is a standard library available to all languages using the .NET Framework. In order to make the programmer's job easier, .NET includes the BCL in order to encapsulate a large number of common functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation. It is much larger in scope than standard libraries for most other languages, including C++, and would be comparable in scope to the standard libraries of Java.

Framework Class Library:

The .NET Framework Class Library (FCL) consists of a series of classes, interfaces, and value types that can be used to program with. The .NET Framework has types that allow one to easily:

Create extravagant graphical user interface applications
(System.Windows.Forms)
Access and manipulate data in various database formats (System.Data and System.Xml)
Dynamically query type information (System.Reflection)
Perform basic Input/Output operations (System.IO)
Perform operating system security checks (System.Security)
Create internet enabled applications (System.Net and System.Net.Sockets)
Create dynamic web based applications – also known as ASP.NET (System.Web)
Access basic data types, event handlers, and exceptions (System)

what is different between BCL and FCL in dot net (.net)?

BCL , FCL both are not same. The Base Class Library (BCL), sometimes incorrectly referred to as the Framework Class Library (FCL) (which is a superset including the Microsoft.* namespaces), is a library of types available to all languages using the .NET Framework. The BCL provides classes which encapsulate a number of common functions such as file reading and writing, graphic rendering, database interaction, XML document manipulation, and so forth. The BCL is much larger than other libraries, but has much more functionality in one package. The BCL would include everything in mscorlib and system and possibly some additional assemblies. It includes all the type, assembly, reflection and collection classes of the framework (among others). It does not include ASP.NET, ADO.NET, WinForms, management namespace and other classes/namespaces that provide additional functionality.

FCL = All namespaces (entire framework).

BCL = Common namespaces (core framework).

FCL = BCL + everything else that ships as part of the .NET Framework.

Difference between String and StringBuilder

C# and Java What is the difference between String and StringBuilder classes?

String is an object. Both String and StringBuilder class stores strings

String :

String is immutable i.e. Read only, non updatable.

Example: String somename = "Lavakumar";

We cannot change a String object after creating one.It means we can’t change the value internally.

If you want change the value of somename object a new object is created then the reference of somename object is changed to new object. The old object is collected by GC ( garbage collecter).

Example: String somename = "sangeetham";

New object with value “sangeetham” is created. Then the reference of somename variable changed from “Lavakumar” object to “sangeetham” object. And the old object “sangeetham” is collected by GC (garbage collector).

Example:

using System;

sing System.Text;

public class string

{

static void Main()

{

DateTime start = DateTime.Now;

string x = "";

for (int i=0; i < 100000; i++)

{

x += "~";

}

DateTime end = DateTime.Now;

Console.WriteLine ("Time taken: {0}", end-start);

}

It takes nearly 10 seconds. Double the number of iterations, and it takes over a minute.

The problem is that strings not changeable (immutable). Just because we're using "+=" here doesn't mean the runtime actually appends to the end of the existing string. In fact, x += "!"; is absolutely equivalent to x = x+"!";. The concatenation here is creating an entirely new string, allocating enough memory for everything, copying all the data from the existing value of x and then copying the data from the string being appended ("~"). As the string grows, the amount of data it has to copy each time grows too, which is why the time taken didn't just double when I doubled the number of iterations.

String Builder :

String Builder is mutable i.e. subject to change.(we can change the value, updatable)

Default some space is allocated for String Builder.

If you are using for loop definitely go to stringBuilder.

It gives better performance when we are adding more than 10 strings.

In this there is no object creation for each addition. So String Builder is faster than String.

String builder initially some default memory.

By using StringBuilder.Append() method we can append Strings.

Example:

using System;

using System.Text;

public class stringbuild

{

static void Main()

{

DateTime start = DateTime.Now;

StringBuilder builder = new StringBuilder();

for (int i=0; i < 100000; i++)

{

builder.Append("~");

}

string x = builder.ToString();

DateTime end = DateTime.Now;

Console.WriteLine ("Time taken: {0}", end-start);

}

It takes nearly 30-40ms only. The time taken is roughly linear in the number of iterations (i.e. double the iterations and it takes twice as long). It does this by avoiding unnecessary copying - only the data we're actually appending gets copied. StringBuilder maintains an internal buffer and appends to that, only copying its buffer when there isn't room for any more data. (In fact, the internal buffer is just a string - strings are immutable from a public interface perspective, but not from within the mscorlib assembly.) We could make the above code even more efficient by passing the final size of the string (which we happen to know in this case) to the constructor of StringBuilder to make it use a buffer of the right size to start with - then there'd be no unnecessary copying at all. Unless you're in a situation where you have that information readily to hand though, it's usually not worth worrying about - StringBuilder doubles its buffer size when it runs out of room, so it doesn't end up copying the data very many times anyway.

visualized comparison of both:

no of iterates

( blue)is the performance of the pure String approach.

(red) is StringBuilder at its basic settings.

(green) represents a StringBuilder initialized to the size of the final string.

StringBuilder performance can sometimes be a bit tricky because there’s kinda “break-even-point” you always keep in mind.

Conclusion:
If you have to concatenate a string more than 10 times, it’s better to use StringBuilder.

Java difference between thread start vs run methods

It is very impotent to know the difference between thread start run methods. both will executes the same run method. There is some very small but important difference between using start() and run() methods. Look at two examples below:

The result of running examples will be different.

Example : 1

Thread one = new Thread(); Thread two = new Thread(); one.run(); two.run();

In This Example the threads will run sequentially: first, thread number one runs, when it exits the thread number two starts.

Example : 2

Thread one = new Thread(); Thread two = new Thread(); one.start(); two.start();

In This Example both threads start and run simultaneously.

Example : 3

public class TesTwo extends Thread {
    public static void main(String[] args) throws Exception{
        TesTwo t=new TesTwo();
        t.start();
        t.run();
        doIt();
    }
public void run()

{
System.out .println("Run");
}
private static void doIt()

{
System.out.println("doit. ");
}
}

Output:

Run
Run
doit.

In this example the start(public void run()) and run methods will executes simultaneously.Because after execution of start statement there are two simultaneous ways.

t.start();

t.run(); public void run()

the two lines will executes simultaneous . so the output will print Run Run in output. after completion of public void run method then controller will return to doIt method. At last the method do It will execute.

Example : 4

public class TesTwo extends Thread {
    public static void main(String[] args) throws Exception{
        TesTwo t=new TesTwo();
        t.run();
        t.start();
        doIt();
    }
public void run(){
    System.out .println("Run");
}
    private static void doIt() {
        // TODO Auto-generated method stub
        System.out.println("doit. ");
    }
}

Output:

Run
doit.
Run

In this example the run method will executes synchronously.so the in output it prints first line "Run". Next start and doit methods will executes simultaneously.Because after execution of start statement there are two simultaneous ways.

t.start();

doIt(); public void run()

the two lines will executes simultaneous . so the output will print " doit. Run" in output second and third line.

Conclusion: The start() method call run() method asynchronously does not wait for any result, just fire up an action), while we run run() method synchronously - we wait when it quits and only then we can run the next line of our code.

Start()--> asynchronous.

run() -->synchronous.

Design Patterns (VTC Video Tutorial) Training

Design patterns let programmers avoid re-inventing the wheel. The original book (Design Patterns by the "Gang of Four": Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides) was phenomenally successful. When the programmer faces a particular problem, all they have to do is to look up the correct matching design pattern and use it to implement the solution. In this tutorial VTC author Steve Holzner guides you through the most popular and useful design patterns, so you can begin incorporating them into your own code.
