Which Java download do i need ?

Java is an important programming language needed to run different websites and applications. However, the installation of Java on your system is quite easy and free of cost. The Java executable file is available for download on the official website free of cost. Now the big question is which Java download do you actually need.
The version of Java you need for your system depends on the operating system that you have. The latest Java update Java EE 7 has been released on October 27th 2013 following the earlier release Java SE 7 on July 28th 2011. However, the latest version is not compatible with all 32 bit operating systems; it is mainly for the 64 bit operating systems.

The installation of Java for different operating systems:

Windows 64 bit:

The latest version of Java is highly compatible with Windows 64 bit operating system and is easy to download and install. The installation of Java for Windows systems is possible both online and offline:

Online installation:

Online installation of Java for your Windows system is the easiest means to get Java Runtime Environment in your computer. The process for installing Java online is as follows. It is better if you turn off your internet firewall before starting the installation as in some cases it tends to interfere with the installation. You can also add exceptions for Java in your internet firewall.
The next thing you need to do is to visit the official website and navigate to the manual download page. Here you will have to click on Windows online option to start the process of installation. The file download option will offer you to either run or save option. If you want to install it immediately click run. If you wish to save the file for later installation click save. The executable file will be saved at your desired location.
When the installation process starts you can see a window where you will have to click on the install button. Because of Oracle’s partnership with different companies you might be presented with several optional third party installations. You can choose whether to install them or not. After that click next and the installation process will start and will complete in a few minutes. It will fetch the required files for installation from the internet so it is necessary to stay connected to the internet while the installation process is running.
To enable Java for your existing browsers you might need to restart your browsers. It is always better to close any open browser before starting the installation process for better integration.

Offline installation:

It is also possible to install Java offline without the need of internet connection. For this you need to get the executable file from the official website. The file is available on the manual download page under the Windows offline option.
Once you get the executable file you can run the same on any Windows computer without the need of internet connection. The executable file contains all the necessary files needed for Java and therefore you don’t need to stay connected to the internet. The remaining process is same as online installation.
However, it should be kept in mind that for both online and offline installation of Java you need to have Administrator privilege before you start the process of installation.

Java for Mac OS X:

You can also install Java on your Mac OS X. For the installation of Java 7 you need Intel-based Mac OS X with version 10.7.3 or above. Similar to Windows operating system it also requires Administrator privilege for the installation. It should also be kept in mind that Java on Mac OS X only works with 64 bit browsers like Safari or Firefox. 32 bit browsers like Chrome etc do not support the Java 7 version on Mac OS X.
For installation you need jre-7u6-macosx-x64.dmg file which can be downloaded from the official website. The license agreement and its terms must be reviewed and agreed before you can download the file. Once done you need to double click on the file in order to launch the file.
Once it is launched the package icon must be double clicked to start the installation process. It will display the Welcome to Java 7 screen where you will have to click continue. On standard installation on Macintosh HD you need to click on the install button. Once the installation is finished you need to click close to complete the process ofinstallation.

Java for Linux systems:

You can also install Java on Linux systems as well. There is the availability of two types of packages for installation. One is Java on Linux platforms which is an archive binary file which can be used by anyone at any location where you are able to write. It does not require the root user for the installation. However, the root user is only capable of installing Java into the system location.
The other is the Java on RPM-based Linux platforms. Linux platforms like SuSEand Red Hat uses RPM based 32-bitLinux platforms. For this type of platform a RPM binary file (.rpm) is needed to install Java in the system location. It is essential to be the root userin order to have this installation done in the system location.
You need to download the packages that meet your requirement for the installation of Java on your Linux platform.

Java for Solaris:

Like other operating systems you can also install Java on Solaris systems as well. It requires Solaris SPARC or Solaris x86 for the installation of Java. It is possible to install anarchive binaryJRE file to any location where you are able to write on a Solaris Platform along with the System version of Java. It should be kept in mind that using this process will not replace the System version of Javawhich is provided by Oracle Solaris OS.
Therefore, the fact is that the Java version and the process of installation of Java varies with the operating system you are using. You need to make sure which Operating system or platform you have in order to follow the exact steps needed for the installation.
