Difference between UTF-8, UTF-16, UTF-32 character encoding

What this means is that UTF-32 will always use 32 bits to represent a unicode code points, those +U numbers, while UTF-8 can take 1 to 4 bytes to represent a character, and UTF-16 can take either 2 or 4 bytes.

10 Books Every Software Engineer and Developer Should Read
There is saying that you can only learn a limited things if you always learn from your experience, but if you learn from other's experience there is no limit. Programming is the field where you must learn from other's experience, and what could be the better ways then reading books, written by those great programmers. This is my list of 10 books every programmer should read, I have read them and they have made huge difference. Sometime I regret why I didn't copy of clean code when I started my career as programmer, because its a master piece and goes a long way to make you a better programmer.

Do you know that an NRI needs to pay tax on his foreign income if his status is not NRI in a financial year. You can avoid tax on your global income at higher tax rate of India by carefully timing your departure and arrival so that you remain NRI in that financial year. #NRI   #Tax   http://savingsfunda.blogspot.com/2015/08/how-nri-can-avoid-tax-on-foreign-income.html

One of the nightmare of Java developer is java.lang.UnsupportedClassVersionError: Unsupported major.minor version 51.0 error, which comes due to incompatible version of JDK and JRE at compile and run time, but upgrading to latest JRE is not the only way to solve this error. You can solve this problem without installing new JRE and just changing your compile time setting to use -target option to produce class files for your production version of JRE. Since upgrading to new Java version is often not easy, especially at big companies , this handy tip will save you from trouble. #java

Difference between Factory pattern and Dependency Injection?
One of my reader  asked me about this beautiful question couple of days back. I hope you will find your answer about dependency injection vs factory pattern in this article. In short, DI is way better than Factory pattern and should be used when available. It makes unit testing easier which leads to better design and quality code.

#Java   #Programming  
TL;DR Main difference between dependency injection and factory pattern is that in case of former dependency is provided by third party (framework or container) while in case of later dependency is acquired by client class itself. Another key difference between them is that use of dependency ...
