Various Applications Java Program

Before discussing the java application program, it helps us see the first little bit about java and java programming language.

What is Java?

Java is a name that actually has many meanings. Java as a British term for Java, or Java as a computer application. However, in Indonesia, Java is more often associated with existing applications on the computer. Namely, the Java programming language, Java platform, and applications created from the Java programming language and runs on the Java platform.

Java Programming Language


The Java programming language is a programming language developed by James Gosling at Sun Microsystems who is now a subsidiary company owned by Oracle Corporation. This language was released in 1995 and became a core component of the Java platform created by Sun Microsystems.

This language is a language derived C and C + +, but has a simpler object model and a low-level facilities less and are general purpose, class-based, and object-oriented. Programs that are created using the Java language implementation dependent as little as possible to the operating system.

Principle of "Write once, run anywhere" is the philosophy of creating an application using the Java language. Thus, the goal of the Java language is an application platform and can run on any operating system (to be multiplatform). Hence also, the Java language has become the most popular language in the world.

Java Platform

As a platform, Java is known as the JVM or Java Virtual Machine. Called the Virtual Machine because the concept is similar to an emulator. Before you run Java applications, operating systems must have had a runtime for the Java Virtual Machine. If this is already installed, you are free to run any Java application.

Fortunately, most operating systems have included the Java runtime in the accessories. Even so, update the JVM is needed to maintain stability and compatibility of the JVM itself to various changes, developments, and improvements.

Java Application Programs

Applications or programs that are built using the Java programming language called Java application. Excellence program Java applications compared to applications built using another language is broad compatibility across multiple platforms and operating systems.

The concept of "Write once, run anywhere" means that once the program was written, you can run it at any point during the platform and operating system supports Java applications and the JVM. This is different from programs written using other programming languages like C, C + +, or Visual Basic.

Java or Java?

Many are still wondering, why this language called Java? Whether Javanese or descent Gosling Java? Apparently nothing. Java is the language of Anglo-American slang meaning 'the coffee, coffee beans'. From here, you'll be able to guess why the logo used by the language or the Java platform is a cup of coffee.


Some Examples of Java Application Program

1. Opera Mini

Who is not familiar with Java applications made in this Opera? Almost every phone that has a Java application and access a GPRS or 3G will have this feature-rich browser. In fact, the Nokia Communicator 9300 and 9500 series fitted with this application as a standard feature.

Opera Mini itself is the result of imports of the Opera program is also quite popular on the PC platform. Opera application residing in the PC platform itself was originally a Java application before eventually patented a specific platform applications.

2. eBuddy

Communities know eBuddy as chat programs. Indeed, eBuddy is more accurately described as a messenger application. Messenger is the kind of applications that help users write to each other messages with another person who has an account that is registered on the same domain. Like Yahoo Messenger or Facebook. EBuddy addition there are various other applications which is also a messenger application. For example, Pidgin, and mig33.

3. ThinkFree Office

Office applications suite similar to Microsoft Office was built using the Java language. This application was made by Haansoft Thinkfree Co., Ltd.., A subsidiary of Haansoft Corporation. This application has two versions: online and offline.

ThinkFree Office ThinkFree Office Online is an application that affixed to the website. This version is similar to Google Docs, the office application package which can be accessed online.

Its offline version sells for 42 Euros. Offline version similar to the online version. The only difference is the purposes of using the internet connection to open, edit, and save the file. In addition, the price is cheap enough to be a choice to rival Microsoft's Office that the price is still exorbitant.
