Can some one give real life example to understand access specifiers in JAVA?

Hello Guys,

Today morning I came across very good information about Object Oriented Programming (OOP) on Quora. I am very excited to share this with you all. As this is not my article, I would like to many thanks to author Pritam Kumar. To read the original post, Can someone give real life example to understand access specifiers in JAVA?

When you update your Facebook Status, it gives you 4 options

1. If you make this status visible for Public, anyone can see this status on Internet (Anyone On or Off Facebook). [Public Access Specifiers]

2. If you make this status visible “only for me”. No one can see this status except you. [Private Access Specifiers]

3. If you make this status visible for Friends or Friends of friends, then your status will be only visible for your friends and your friends friends. Not everyone presents on Facebook or Internet. [Protected Access Specifiers]

4. If you make this status visible for “Friends”, then your status will be only visible for your Friends. Not your friends of friends or everyone presents on Facebook. [Default  Access Specifiers]

In Programming Terms:

There are four Access Specifiers in Java.

1. Public
2. Private
3. Default.
4. Protected

Hope this little information will help you. Feel free to add your valuable comments.
Happy Coding! Stay tuned…

Android Studio – Shortcuts and Cheat Sheet

Form past couple of weeks on have been working on Mac machine. Those who coming from a windows background may jumble initially on Mac while development (I am one person among those).

We didn’t do anything wrong, but somehow, we lost..

During the press conference to announce NOKIA being acquired by Microsoft, Nokia CEO ended his speech saying this “we didn’t do anything wrong, but somehow, we lost”. Upon saying that, all his management team, himself included, teared sadly.

Nokia has been a respectable company. They didn’t do anything wrong in their business, however, the world changed too fast. Their opponents were too powerful.

They missed out on learning, they missed out on changing, and thus they lost the opportunity at hand to make it big. Not only did they miss the opportunity to earn big money, they lost their chance of survival.

The message of this story is, if you don’t change, you shall be removed from the competition.

It’s not wrong if you don’t want to learn new things. However, if your thoughts and mindset cannot catch up with time, you will be eliminated.

1. The advantage you have yesterday, will be replaced by the trends of tomorrow. You don’t have to do anything wrong, as long as your competitors catch the wave and do it RIGHT, you can lose out and fail.

2. To change and improve yourself is giving yourself a second chance. To be forced by others to change, is like being discarded.

Those who refuse to learn & improve, will definitely one day become redundant & not relevant to the industry. They will learn the lesson in a hard & expensive way.👌

There is one MainActivity and inside the MainActivity there is one Fragment, which is a container…

Applying MD5 Algorithm In Android


Hello developers, have you ever given a thought about securing your content when it is being used in communication? If yes then this blog might help you in achieving so.

MD5 stands for Message Digest(5 denotes the series), which is a hashing algorithm used for generating the fingerprint of the content. It was designed in 1991 by Ronald Rivest at MIT.

MD5 algorithm is a one way hashing process which means you cannot generate original text from the hash code.It always produces the same output for the similar input, and this property is used for checking the data integrity. You can compare the two hash codes at destination(one which is received from server and one which is already present at destination) and check whether the files contains the same content or not.
