Developed by Sun Microsystems, Java is a group of several computer software and specifications and later acquired by Oracle Corporation. Java offers a system for developing application software and using it in a cross-platform computing environment. Java is utilized in a wide range of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Although less typical, Java applets run in secure, sandboxed environments to give many features of native applications and can be embedded in HTML pages.
Java can be used via Desktop. According to Oracle, the Java Runtime Environment is found in more than 850 million PCs. Microsoft has not grouped a Java Runtime Environment or JRE with its operating systems because Microsoft was sued by Sun Microsystems for adding Windows specific classes to the bundled Java runtime environment and for implementing the new classes available through Visual J++. Currently, Apple no longer includes a Java runtime with OS X since its version 10.7. However, the system asks the user to download and install it the initial time an application needing the JRE is started. Many Linux distributions have the partially compatible free software package GNU Classpath and more compatible IcedTea.
A couple of Java applications are in relatively widespread Desktop use, including the Eclipse and NetBeans integrated development environments and file sharing clients like Vuze and LimeWire. Java is also utilized in the MATLAB mathematics programming environment, for rendering the user interface and as a component of the core system. Java gives cross platform user interface for a couple of high end collaborative applications such as Lotus Notes.
Java is also being utilized in mobile devices. Java ME has become well known in mobile devices, where it competes with BREW, Symbian, and the .NET Compact Framework.
The different ranges of mobile phone manufacturers has created a need for fresh unified standards so programs can work on phones from different suppliers.
For example, the Android operating system of Google uses the Java language, but not its class libraries. Hence, the Android platform cannot be called Java. Android executes the code on the Dalvik VM and not the Java VM.
Java is also used for web server and enterprise. The Java platform has become a regular of enterprise IT development after the introduction of the Enterprise Edition in 1998, in two different ways.
In order for you to download Java, all you would require is a computer or a mobile device with an Internet connection. You would also need an existing web browser program like Google Chrome, Mozilla Firefox, or Internet Explorer.
The main benefit of a Java download is that it can be used at any type with any device and any kind of platform, for that matter.
• Open a web browser program and go to the Google home page at www.google.com. For your java.com download, type “Java” and click on the “Download Free Java Software” search result. Moreover, you can also go straight to www.java.com/download.
• Note there is no guarantee that the page will look like it does in picture number 1.
• As soon as you have loaded the site, you will see the java.com download page as in picture number 2. Click on the “Free Java Download” link.
• Afterwards, depending on your device and operating system, you will then be shown this next page in picture number 3. Click on “Agree and Start Free Download.”
• As soon as you have saved the file, give it some time until it downloads on your device. Once it has saved on your device, double click on the executable file icon (the name would differ depending on which web browser program you use), such as in picture number 5.
• Based on your security settings, your computer will ask if you want to run the executable file. Just click on the “Run” link if it does show up. This is usually the case even if it is just a Java test.
• You have to make sure that you are connected to the Internet throughout, as Java will guide you through the installation process of Java or a Java update or even Java updates on your device. We say updates since you may be running an older Java version and may need an update. As soon as you are finished, we give you our congratulations, you have successfully downloaded Java!
