Facebook profile picture privacy revealed!

Recently, while going through the Facebook Developers API documentation I have found out few flaws in the facebook privacy. The flaws exist in the privacy of profile pictures. It is very easy to view the likes on the private facebook profile pictures and also you can view that profile picture in full dimensions by doing these tricks. Seriously it could lead to a misuse of many private profile pictures. Facebook need to consider this issue as early as possible. All that game of URL is. You just need to tweak the Fields and values in the Facebook URL and you can end up with unexpected and weird results and two of which I found while doing those insane tricks. I have written this post to inform the facebook users about this privacy breach before their pictures get into the criminal hands and even more serious could happen using that. By doing two of the following things you can do some insane, unexpected tasks!

Viewing the Private Facebook Profile picture in full dimensions:

• Go to the desired facebook profile.
• Right click on the profile picture and click on "Copy image URL" or "Copy Image Location".
• Paste the URL up on the URL bar.
• The URL will look like this.
• https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/c120.0.720.720/s160x160/111111_123456789876543_1111111111_n.jpg
• Remove the following portion from the URL.
• /c120.0.720.720/s160x160.
• The final URL will look like this.
• https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/111111_123456789876543_1111111111_n.jpg

Now open this URL, you will get the results.

Viewing the likes on the private facebook profile pictures:

• Take the url:
• https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/111111_123456789876543_1111111111_n.jpg
• Copy the following portion between two underscores
• 123456789876543
• Paste the above code at the end of the following URL.
• www.facebook.com/browse/likes?site=asd&id=
• The final url will look like this:
• www.facebook.com/browse/likes?site=asd&id=123456789876543
• Paste this URL in the browser URL bar and you will see the likes on that private profile picture.


Note:
You need to log in the Facebook to get the final results.

Static block in Java

Static block

Static blocks in Java are initialize before any objects.They can access only static data types that are declared global or are instance variables. But can declare local variables of non-static within their scope.

Example

public class StaticDemonstration {

 static int a;
 static{
  System.out.println("Hello Static");
  a=10;
 int b = 10;
 System.out.println(a==b ? "Right":"Wrong");
 }
 
 public static void main(String[] args) {
 //No Objects
 }

}

Output

Hello static
Right

Easy Use of switch in Java!

Switch

Switch is used as an alternative of if else series of statements. It is more efficient and easy to use than if else if ladder.

Syntax

Switch value{body.. }

Test application

I am going to create a test application in Java using switch that will allow the user to enter any integer numbers from 0 to 10 and the program will produce output in alphabets against any number entered.

import java.util.Scanner;


public class SwitchDemo {

 
 public static void main(String arg[]) {
  
  
    
  System.out.println("Enter the Number to convert " +
    "in alphabets");
  Scanner in = new Scanner(System.in);
  int a;
  do{
   a = in.nextInt();
  
  
   switch(a){
   case 0:
    System.out.println("Zero");
    break;
   case 1:
    System.out.println("One");
    break;
   case 2:
    System.out.println("two");
    break;
   case 3:
    System.out.println("Three");
    break;
   case 4:
    System.out.println("Four");
    break;
   case 5:
    System.out.println("Five");
    break;
   case 6:
    System.out.println("Six");
    break;
   case 7:
    System.out.println("Seven");
    break;
   case 8:
    System.out.println("Eight");
    break;
   case 9:
    System.out.println("Nine");
    break;
   case 10:
    System.out.println("Ten");
    break; 
   default:
    System.out.println("Wrong input");
    break;
   }
  }while(a<=10); 
    
   
   
  }
  
 }
