Does Microsoft show us a Glimpse of the Future from the Metro Look

Microsoft has always known what its user needs and has attained massive success introducing products which full fills the trend and requirements.It has recently introduced the Windows 8 and  Outlook.Both these products have a common feature the Metro look.

So what is this Metro look and why have they used it?






The Metro is a User Friendly Minimalistic and Stylish Graphical User Interface(GUI) Unlike the predecessor Windows versions you can see that there is no Windows start Button and the detailed lists of icons.Everything is clean and minimal.This is a trend that has been absorbed from the growing Android Smartphone and Tablets Market.Windows 8 also aims the users who uses Mobile Devices with touchscreens.The Interface is good and is fluid.

Microsoft has also done a good job with their Online Mail Service,its also been ported to the Metro Look.
Live.com and Hotmail.com has been revamped to the simpler and user friendly Mail Service Outlook.com

These are all very good and the Outlook Mail service is very attractive,Expect it could have been much faster or it could show the loading screen like Gmail do when you open your Mail account.

These all are revolutions in the IT Era-User interfaces are becoming simpler and simpler by time,user hardly needs to do something,its becoming very easy for the naive user.But advanced users might find these simplicity a little annoying as they may be interested to explore Details of the System.

These all make up an Efficient and Intelligent approach  that makes Information Retrival and Information processing a Child's Play and the only doubts remains-Will a time come when computers do all the work that we think of ????

Java Program to Write Lines of Text to a File + Source Code

To learn the Basics of file manipulation in java ,the best way to start is by writing simple code to write some text to file.The following is a sample program that writes text to file using BufferedWriter Class

It uses the File Class to open the File to the BufferedWriter Class,which writes some sample text to the file.The main class used is the Writer Class intended for writing stream data to files.

Below is the complete source Code to implement a Simple File Writer in Java

 import java.io.*;  
 public class FileWriter {  
  public static void main(String[] args)throws IOException{  
  String towrite = "Hello World";  
  Writer data = null;  
  File file = new File("myfile.txtt");  
  data = new BufferedWriter(new FileWriter(file));  
  data.write(text);  
  data.close();  
  System.out.println("Text Written");   
  }  
 }

Simple Pencil Sketch Java Applet Example+Source Code

Java Applets are easy to Implement Web Programs that can be run on the browser without any installation or downloads. The only requirement is that Java Virtual Machine(JVM) Should be installed on the END User Machine. As you may know Java Applets are OS Independent it can be run on any system supporting Java.

Simple Pencil Sketch Applet in Java

The following is a simple Java Example Applet that draws Lines when a user clicks and Drags the mouse.

It uses mouseMoved, mousePressed events to Track mouse clicks by using the MouseAdapter Motion Listener Class.The following is the screenshot of the Applet

The following is the complete Example Source code for the Pencil Sketch Java Applet

 import java.applet.*;  
 import java.awt.event.*;  
 import java.awt.Graphics;  
 import java.awt.Color;  
 //<applet code=LineDraw.class width=400 height=300> </applet>  
 public class LineDraw extends Applet implements MouseMotionListener  
 {int x1,y1,x2,y2;  
  boolean flag=false;  
 public void init()  
 { x1=0; y1=0;  
  addMouseMotionListener(this);  
  addMouseListener(new MouseAdapter(){  
  public void mousePressed(MouseEvent ME)  
  { x1=ME.getX(); y1=ME.getY();}  
  }  
  );  
 }  
 public void mouseMoved(MouseEvent ME)  
 {showStatus(ME.getX()+","+ME.getY()); }  
 public void mouseDragged(MouseEvent ME)  
 {  
  Graphics g=this.getGraphics();  
  x2=ME.getX();  
  y2=ME.getY();  
  g.drawLine(x1,y1,x2,y2);  
  x1=x2; y1=y2;  
  }  
 }  

.Net 4.5-The End of Microsoft .Net Framework Client Profile

Microsoft had introduced 2 Variants of the .net Frameworks till .Net Framework Version 4,the Complete Framework and the Client Profile which was only a subset of the the Complete Framework.

Why did Microsoft do it?

Since the Complete Framework had a large size Microsoft did not want the END user's to consider it annoying to download the complete framework to run applications developed in .Net.
Certain software's only used some parts of the framework.So client profile was created as a subset of the .Net Framework complete Edition.The client Profile did not support ASP.Net and the Advanced Web Programming.

Was Client Framework a Success?

The Straight forward answer is 'NO'.If you ask why just compare the size of the two packages.

 .NET Framework 4 32BIT + 64 bit Full  - 48.1 MB
 .NET Framework 4 Client Profile-   41.0 MB

Just a 7MB Difference.So this is where it failed,the users will find it comfortable to download the full framework as the sizes have a small difference.This also created confusion among common users regarding the different terms used.

But with the Release of the .NET Framework 4.5 Microsoft is putting an End to the Client Framework model.Microsoft has mentioned about this in their MSDN Article http://social.msdn.microsoft.com/search/en-us?query=compact+&x=0&y=0

Quoting from MSDN

Starting with the .NET Framework 4.5, the Client Profile has been discontinued and only the full redistributable package is available. Optimizations provided by the .NET Framework 4.5, such as smaller download size and faster deployment, have eliminated the need for a separate deployment package. The single redistributable streamlines the installation process and simplifies your app's deployment options.

 Thus us Developers and END Users will find it comfortable to download a single version rather than getting confused with all different versions around.

Program to Implement Selection Sort in Java+Explanation

Selection sort is said to be an efficient algorithm when considering small computations involving limited memory/resource but it is quite inefficient when compared to other techniques when huge computations are required.Selection sort is said to be efficient for small list of items because of its simplicity.

The following steps Explains the working of the Selection sort Algorithm

1. Obtain the Item with the Minimal value from a List/Collection of items
2. Swap the item with the Item in the first position of the Collection/List
3. Repeat the Process for the rest of the Items in the Collection

The Following is the Complete Program Source Code in Java for Implementing Selection Sort Algorithm

 import java.io.*;
import java.lang.*;
class array
{
 DataInputStream get;
 int a[];
 int i,j,n;
 void getdata()
 {
 try
  {
   get=new DataInputStream(System.in);
   System.out.println("Enter the limit");
   n=Integer.parseInt(get.readLine());
   a=new int[n];
   System.out.println("Enter the elements in the array");
   for(i=0;ia[j])
   {
    temp=a[i];
    a[i]=a[j];
    a[j]=temp;
   }
  }
 }
 System.out.println("Elements in ascending order is:");
 for(i=0;i=0;i--)
 System.out.print(" "+a[i]);
 }
}
class selectionsort
{
 public static void main(String arg[])
 {
  array obj=new array();
  obj.getdata();
  obj.sorting();
 }
}
