Java is widely and high competitive words on Google or any other search engine. Today for online business application, java is the best option. When you find the sentence like we offer java solutions then you confuse obsessively why not. Java solutions mean use java and its latest technologies for web development, software development, Enterprise management software development, and mobile application development. However, you have one questions how all above development is possible through java. Not worry its can developed using latest java technology tools and frameworks like eclipse, struts, J2ME, J2EE, J2SE, JDBC etc.
Java is widely used for web application development like e-commerce application, online shopping cart, dynamic website, blog etc. Web application using java is more secure, reliable, and robust then PHP and.net solutions. Today many big business owners or company would like to make their e-commerce web application through they sell their products or services across the world. However, security is main point for any e-commerce application because if you have popular then its chance to theft your transaction, important details for customer, products etc. So as per my way java is the best option for e-commerce application.

What is Java Object Initialization?
The concept of object in a broad sense can be described as a collection of data along with the methods to manipulate the corresponding data. The Objects are be loaded into the memory before processing. In main memory the object has a state determined by its instance variables and their values, which can be processed and evolved throughout its lifetime. The newly-created object should have a newly-allocated memory( heap) to accommodate the object's instance variables, this is done by Java virtual machine (JVM).
Object initialization is very important in programming, as it is a common source of bugs. The Java Programming language provides different built-in mechanisms to ensure proper initialization of the memory occupied by a newly-created object, there by helping the objects to get a valid initial state.
The Java Programming language offers three mechanisms to ensure proper initialization of newly created objects.
* Constructors.
* Instance variable initialization.
* Instance initialization.
When we are creating an object using new operator or the new Instance() method of class, JVM allocates memory for it, then Java virtual machine will run the initialization code before we use the newly-allocated memory.
Constructors
Constructors are methods, with a set of parameters and a body of code and has the same name as the class but has no return type. The constructors can be overloaded by varying the number, types, and order of parameters. When we are creating new instance using new keyword we often provide a constructor that initialize the Object. If we are using class that has no constructor defined, the compiler will automatically generate a default constructor for the class. This constructor has no parameter and has empty body, this ensures that each class has at least one constructor.
class Demo
{
int a;
public Demo()
{
// the initialization code for instance variables
a=0;
}
}
Instance variable initialization
In an instance variable initialization method java uses an equals sign and expression technique to initialize the instance variable.
class Demo
{
private int a = 1; //this evaluate a with a value of 1
}
Instance initialization
Instance initialization is also known as instance initialization block, which is one of the alternatives to Instance variable initialization. It is very useful in following situations
* Initializer code need to catch exceptions.
* Initializer code need to do calculations that can't be expressed with an instance variable initializer.
* If class has multiple constructors - no need to repeat the same initializing code in all constructors.
* When we use anonymous inner classes, which normally do not have constructors.
class Demo
{
private int a;
//intializer
{
a=2;
}
}
One of the main properties of initializers is they cant make forward reference, as the initializers are executed in textual order.You have to make sure that the referring of instance variable should be only after it is initialized.
Default initial values
If we are not providing any explicit initialization method to variables including instance and class variables, they will be initialized according to their type. Each data type has its own default initial values. The local variable must be initialized explicitly before use.
e.g boolean-false
int - 0
Java's initialization mechanisms help the programmer to ensure that objects we design have a valid and predictable state.

Introduction to Java Concurrent Programming
When computers didn't have operating systems yet, they executed only one program at the time. The program would run from the beginning to the end. Running only one program was the only way back then, and this is now seen as very inefficient. Because the program had access to all the resources in the computer at any time, programming was a lot simpler. But because the machine (computer) was only running once program at the time, the machine's resources where not used efficiently, resulting in an inefficient use of the computers capabilities. Nowadays, machines are able to run multiple programs. The OS (operating system) can even run multiple programs simultaneously, and one single program can even be divided into multiple concurrent threads. All these threads together do all the work that used to be done by just one program. Threads can also communicate with each other, with for instance; message passing and shared memory concurrency.
The last few years, multicore processors have become less expensive. Most desktop computers and laptops are using multicore chips and developers are programming more and more with multiple concurrent threads. A downside is that the bug reports related to threading are also increasing every day; this shows that multicore programming is not the easiest thing to do. In Java, concurrency bugs are one of the most painful problems and in many occasions they are highly unpredictable. One of the biggest issues regarding Java concurrent programming is the mind-set of the programmers that doesn't match the concurrency features offered in Java. Programmers need to start thinking about concurrency and parallelism in the foundation of their programs. The Java language provides low level tools for concurrency such as condition waits, synchronization, message passing and resource sharing. The problem is that these tools need to be implemented at application level consistently. The conclusion? It can already be hard to write correct programs, but writing correct concurrent programs is even harder. The right mind-set is needed. The reason behind the high difficulty level is that there are simply more levels where things can go wrong with Java concurrent programming. The reason developers still choose to use concurrency on their programs is because threads are an inevitable feature of the Java language and the easiest way to use the multicore power we see almost everywhere these days. When looking are the future, the only conclusion that can be made is that concurrency programming will become increasingly important with the rising number of cores.

Difference Between Java and WordPress
ava and WordPress are very much different, this is an attempt to compare and see where they intersect each other.
Java
Java is an enterprise Language, what it means it is used to build enterprise applications, what do we mean by that?
· A variety of clients can interact with applications like browsers, smart tablets, B2B applications, .NET and other language apps.
· High Security to support the standards.
· Highly Scalable to support the growing traffic.
· Performance - Begin compile time performance is high.
· E.g applications are Gaming, ECommerce websites, Billing, Retail, CRM and tons of others
Java can be used to create blogging CMS like WordPress. There are CMS's like alfresco, Plone, JRoller whodo to attempt to that, but none has been able so popular as WordPress.
WordPress
Very specialized CMS/blogging engine build on top of PHP.
· It is very easy to learn software, compare it to learning MS Word.
· You don't need to know PHP/programming to be WordPress website developer.
· It has a themes concept, which allows a developer to configure website pages with easy.
· Supports thousands of plugins, almost easy to find any kind of functionality a website needs.
· Installs on Apache Server with PHP engine.
· Many hosting sites support 1 click install.
· Uses MySQL as the backend engine.
As you see, WordPress and Java cannot be compared as one is a language where another is a software built on PHP language.
Had WordPress been written in Java
As a Java Developer, I do wish WordPress was built on Java, it would have given
1. Java applications a web flair, we would have to see all together new set of applications /widgets/ plugins.
2. Designers would have not been scared of the language at all.
3. Applications could have used the WordPress database, which has a very simple schema.
WordPress And Java Together
Resin Quercus
Resin is a Java Application server, but with a twist, it has a Quercus engine which allow PHP applications to installed as Java applications.
What does this mean, if a WordPress can be installed on Resin will run as a Java application and also take advantage of libraries like Spring, Hibernate,SOA.
Also, will definitely perform way better as it will be compiled only once and not be interpreted with every request like it does now
To have this integration working has its own challenges but good news is there is a way.
Summary
While WordPress has it own niche, creating CMS websites with blog functionality, it is the DeFacto Platform.
But when it comes to creating highly scalable enterprise Applications Java is the DeFacto Platform.
