What is the difference between j2se j2ee j2me

J2ME is at the other extreme of the system-size scale. The targeted host platform here is are small electronic devices. Now we are talking about a small, confined and restricted host environments where resource is extremely expensive. J2SE is the plain vanilla Java. J2SE transcends dissimilar applications and provide the least common denominator set of language features and class libraries.

Hope my explanation helps clear your doubts. J2EE stands for Java 2 enterprise edition for applications which run on servers, for example web sites. An applet is a software component that runs in the context of another program, for example a web browser.

A plugin is a computer program that interacts with a host application a web browser or an email client, for example to provide a certain, usually very specific, function "on demand". Is Java a freeware like Linux or so?

J2ME stands for Java 2 micro edition for applications which run on resource constrained devices small scale devices like cell phones, for example games. Netbeans is an IDE Integrated development environment developed in Java which eases your job of application development. Save my name, email, and website in this browser for the next time I comment.

It is a community-driven edition, i. There are also countless languages like. J2SE is used to create applications for Desktop. The software development kits SDKs for the above four platforms are free and can be downloaded from Sun's website.

Of course, using the SDK is not too particular, we need development tools to improve development efficiency. Such a tool is called an integrated development environment IDE. The former is an open source tool written entirely in Java, while the latter is a heavyweight official development tool. Sun's development tools can be described as rooted, and Java programmers can finally bathe in the sun! Learn j2se first. To learn j2ee, you must first learn j2se. At the beginning of learning j2se, it is recommended not to use IDE, and then gradually transition to IDE development.

After all, it is convenient to use it. Learning j2se recommends two books, "java2 core technology one or two volumes", "java programming ideas", "java mode". Among them, "java programming thought" should be studied and intensively read. This period of time is basic skill learning.

The time will be very long or may be very short, depending on the level of the learner. Don't be entangled by the IDE. In the process of learning java and j2ee, you will encounter a variety of IDEs.

Don't be fooled by them. When learning JAVA, you must learn the language itself. Don't pay too much attention to the additional functions of the IDE. The conversion between different IDEs is very easy. Too much care about the functions of IDEs can easily delay the understanding of the language itself.

Just use one of them. It is recommended to start j2ee from eclipse. Because Jbuilder is more suitable for writing j2se programs. Choose and use the configuration of the learning server When you have experience with j2se and IDE, you can start learning j2ee.
