Installing Java for Windows 7
You can install java in your computer using any of the 2 methods below:
Download the online installer
Download the offline installer
The first method is the process of using a boot-strap installation method. The file is small because it will download the necessary files for the detected operating system and type of file system (32-bit or 64-bit). This prevents a mistake in downloading wrong setup files when downloading Java installer from the vendors' website.
The second method is for advanced users that is familiar already what file system of Windows they currently use. Note that a third-party add-on may be offered when you try to install, download or update Java and it depends on your location. Example: A friend of mine who is in the U.S. has seen a third-party add-on when downloading or installing java but here in Asia, I don't see the third-party add-on bundled in java installer or before downloading. The add-ons are not required to install or use Java for Windows 7. Simply uncheck the box to only get Java RE.
Any method you choose to download the installer will let you install java using the same install process. There is no customization to install Java except when you want to change the install directory. Mozilla-based and Internet Explorer browsers will automatically use the plug-in when you visit a website that requires Java plug-ins.
