Java is an object-oriented programming language developed by Sun Microsystems. Similar in syntax and style to the C and C++ languages, Java allows programmers to create applications capable of running on nearly any operating system and platform. As long as the computer has Sun's Java Runtime Environment (JRE) software installed, the Java application will run without issue. Once you understand the proper steps, installing the JRE on your computer is a quick process.
Open a Web browser window and download the most current version of the JRE. Visit the manual download page on the Java website and click the link labeled "Windows 7/XP/Vista/2000/2003/2008 Online."
Click "Run" when prompted by your browser.
Click "Install" on the first setup screen to confirm your agreement with the software's license agreement and begin the installation process. Depending on your operating system version and default Web browser, you may be presented with a screen that allows you to install additional, optional software after clicking "Install." Check the box next to the name of any program you want to install alongside the JRE, and then click "Next."
Click "Close" after the installation process completes to close the installer program. The Java Runtime Environment has been successfully configured on your computer.
- All versions of the Mac OS X operating system come with Java pre-installed. You do not need to download and install the software manually on these computers.
- You may have to close your browser and then restart it before the Java browser plug-in functions correctly.
