There are two types of modifiers in java: access modifier and non-access modifier. The access modifiers specifies accessibility (scope) of a datamember, method, constructor or class. There are 4 types of access modifiers: There are many non-access modifiers such as static, abstract, synchronized, native, volatile, transient etc. Here, we will learn access modifiers.

A package is a group of similar types of classes, interfaces and sub-packages. Package can be categorized in two form, built-in package and user-defined package. There are many built-in packages such as java, lang, awt, javax, swing, net, io, util, sql etc. Here, we will have the detailed learning of creating and using user-defined packages.

Runtime Polymorphism. Let's learn what is runtime polymorphism with suitable example.

A class that is declared with abstract keyword, is known as abstract class. Before learning abstract class, let's understand the abstraction first. Abstraction Abstraction is a process of hiding the implementation details and showing only functionality to the user.

In this page, we will learn how to write the hello java program. Creating hello java example is too easy. Here, we have created a class named Simple that contains only main method and prints a message hello java. It is the simple program of java.

In this page, we will learn about the objects and classes. In object-oriented programming, we design a program using objects and classes. Object is the physical entity whereas class is the logical entity. A class works as a template from which we create the objects.

Let's learn what is naming convention and what are its benefits.

Unicode system is a international standard encoding.Let's learn why unicode is used in java

Java supports two selection statements - if and switch. These statements allow us to control the flow of the program. Depending upon the expressions or values, the corresponding blocks/statements of code will be executed or by passed. The two statements are if statement is a conditional branch statement. This is a two way branch statement. Depending upon the whether a condition is true or false, the corresponding code is executed. switch statement is a multiway branch statement. Depending upon the value used for switching, the corresponding code is executed. These two statements are very powerful and are used widely across any application. They provide effective solutions for branching problems.

Can you write a program to get the Highest Common Factor (HCF) of fractions. { {4 / 5}, {5 / 6}, {14 / 15} } =>1 / 30 { {3 / 13}, {6 / 7}, {18 / 7} } =>3 / 91 { {14 / 39}, {35 / 9}, {28 / 3}, {91 / 11} } =>7 / 1287 { {57 / 10}, {95 / 12}, {133 / 90} } =>19 / 180 {17 / 47} =>17 / 47 Try it here: http://java.meritcampus.com/java_questions/231/try

Does it all make sense now? Do you know how to solve every problem? Probably not, but when it comes right down to it, using Java EE can be even simpler than using Spring, and take much less time. You just have to find the right guides and the right documentation (which is admittedly a severe sore-spot of Java EE; the documentation is still a work in progress, but is getting much better, save blogs like this one.) You have to turn to a vendor like JBoss, or IBM in order to get the use-case driven documentation you need, and they do have documentation, it's just a matter of finding it. Seam 3 in particular strives to give extensive user-documentation, hopefully making things much simpler to adopt, and easier to extend. The main purpose of this article was not to bash Spring, although I may have taken that tone on occasion just for contrast and a little bit of fun. Both Spring and Java EE are strongly engineered and have strong foundations in practical use, but if you want a clean programming experience right out of the box - use Java EE 6 on JBoss Application Server 6 - JBoss Tools - and Eclipse. I will say, though, that the feeling I've gotten from the Spring forums vs the Java EE forums, is that there are far many more people willing to help you work through Java EE issues, and more available developers of the frameworks themselves to actually help you than there are on the Spring side. The community for Java EE is much larger, and much more supportive (from my personal experience.) In the end, I did get my application migrated successfully, and despite these issues (from which I learned a great deal,) I am still happy with Java EE, and would not go back to Spring! But I do look forward to further enhancements from the JBoss Seam project, which continue to make developing for Java EE simpler and more fun. Don't believe me? Try it out. Find something wrong? Tell me. Want more? Let me know what you want to hear.
