Why java is called platform independent language?

Why java is called platform independent language?

By Unknown   23:20   1 comment:

One of the major features of java includes that why java is called platform independent language.

Before understanding this feature we need to know about -

Javac – compiler that converts source code to byte code. 
JVM- interpreter that converts byte code to machine language code. 

As we know java is both compiler & interpreter based language. Once the java code also known as source code is compiled, it gets converted to native code known as BYTE CODE which is portable & can be easily executed on all operating systems. Byte code generated is basically represented in hexa decimal format. This format is same on every platform be it Solaris work station or Macintosh, windows or Linux. After compilation, the interpreter reads the generated byte code & translates it according to the host machine. . Byte code is interpreted by Java Virtual Machine which is available with all the operating systems we install. so to port Java programs to a new platform all that is required is to port the interpreter and some of the library routines.

Source code -> javac ->Universal byte code

Universal byte ->jvm/java -> execute them on a particular machine.

Apple recently pushed the iOS 7 update bringing new user interface with all icons and HD graphics, well not only this they even added some awesome features like the call blacklisting that the one and the best feature added by Apple team. So now you could easily block any contact or unknown number and they would not be able to call you or send you messages and do facetime chat with you.

So now you do not need to install any other blacklisting app on your iOS device but just following below steps would allow you to block the user and that too using the default app and interface.

1. Just open your Phone App > Call Log.
2. Now in this just select the number you want to block and click that i icon on the right side and then scroll down to see the Block this Caller option.
3. Now press that option and then it will slide and say Block Contact, just press that option and that's it your caller will be blocked.
4. So now instead of Block this Caller you will see another unblocking option which says Unlock this Caller, so if you want to remove that caller from the block list just press that option and that caller will be removed from the block list.
5. Now there is another way to see all the blocked users and even unblock them, just navigate to Settings > Phone > Blocked.
6. So now you will see all the callers you have blocked, so swipe left on anyone to unblock them from the block list.

So that ends the tutorial, well remember the caller you will block will not be able to call you, send your messages and chat with you using Facetime, so make sure to only do this to someone who is really harassing you :)

Well first method includes a simple way of logging in to your Google account and then getting RID of that lock pattern but if you have forgotten your email too then the second method could handy that includes executing few lines of script in command prompt which will allow you to write any pattern and to get into your OS and the third one is hard resetting your device and deleting all the users data.

 

#1. Unlock Lock Pattern using Email Option

Well this is easiest and recommend way of getting rid of that lock pattern if it works, so you just need to add wrong pattern for 5 times and then if will show you the Forgot Lock Pattern option, then you can login through your Google account and bypass the lock pattern system on your device.

 

#2. Unlock Lock Pattern using Command Prompt

This is the second way and its confirmed by many online website's that it works great, so lets just hop into the tutorial on how it actually works.

1. Connect your Android Device to your PC.
2. Now open Command Prompt as an administrator.
3. Now type below code into it and press enter. adb shell
   cd /data/data/com.android.providers.settings/databases
   sqlite3 settings.db
   update system set value=0 where name='lock_pattern_autolock';
   update system set value=0 where name='lockscreen.lockedoutpermanently';
   .quit
   
4. Now you will some screen like below and then you can reboot your OS and now when your device boots up again try unlocking your device using any lock pattern and it will work pretty fine.
   
5. If you face any problem repeat same steps but instead of the above code try using adb shell rm /data/system/gesture.key and press enter and now try rebooting your device and see if it works.

#3. Unlock Lock Pattern using Hard Reset Option

So this is the third method and even developers this works like a charm too, well we will be using the inbuilt Android feature that's Hard reset (every phone has this feature) and this will delete all the user's data which will unlocks the device.

Note This method will remove everything from your device except stuff on your SD Card, so make sure you attempt it only if none above method works and you seriously need to unlock your device.

1. Shut Down your Android Device.
2. Now we need to hold few buttons combination in order to get our device booted in, well every phone can have different combination so normally its Volume UP + Power button so try that else use below from popular devices.
   • Nexus 7 - Volume Up + Volume Down + Power
   • Samsung Galaxy S3 - Volume Up + Home + Power
   • Motorola Droid X - Home + Power
   • Now these were the popular phones I know, but you have any other phone and above combination is not working then you can Google your phone combination keys and you will get something for sure :)
3. So now as soon as you see your phone's logo you can release the Power but you should keep holding the Volume Button till you get into the Recovery Mode.
   
4. Now you will see some screen like above just navigate to wipe data/factory reset using volume keys and then press Power button to activate it.
   
5. Now you will get the Yes and No option (Google is creative in this isn't it) so slide down to that Yes -- delete all user data option and press that.
6. Now it will wipe clean your device and will remove all the restrictions and now you can once again login to your OS. Well you can see below video tutorial too for easier access to your recovery mode.

So possibly these were the three methods I think that can be used to unlock your lock pattern on Android Device, well if you think you have some other easiest way then do comment below I will add that method too :)

Facebook security is must these days as hackers are just exploiting you profiles stealing important data and then using to loop into other accounts and do much more cheesy stuff, so we have already posted some security measures you could take to protect your account like using HTTPS connection in facebook and even enabling 2 step verification as soon as it is enabled and even scanning your facebook profile using Safego Bitdefender profile scanner online tool.

So now even logging out from your account as soon as you have done doing everything could decrease the possibility of getting hacked and data theft. So now many times what happens is every time you login to your account and surf other sites you normally forget to logout of your account and anyone coming to that PC could use your account and post anything unknown stuff.

So now to protect all these activities "Facebook Auto Logout" extension pops in making logout step a lot easier and that too automatic. You just need to configure the timer according to your usage, so like it can be configured to logout your account after 10/min or in activity or so, this even logs you out as soon as you close browser.

1. On Chrome install "Facebook Auto Log Out" [Link]
2. On Firefox install "Facebook Auto-Logout" [Link]
3. So after your extensions are installed you would be able to see the icon in your status-bar, so now on Firefox by default the timer is set to 1/min but obviously you can change it accordingly.
4. But if you are one Chrome you need to enable the timer by imputing the exact time you want your Facebook to be logged out, so you won't find any inactivity option for chrome but its straight forward, like you can see in the image on the right.
5. So now just pop in the exact time make sure you fill every field else it will show error, now just start timer and see how automatically you get logged out of facebook.

So now this is the easiest way to log out and protect your facebook profile from preying eyes. Make sure if you are in any cyber cafe , do install these extension first before browsing facebook maybe these could help in getting security tight :)
