Do I need Java on my computer?

Sun Microsystems created Java in 1995 as a universal platform that could run the same application on any machine regardless of its operating system. Java is currently installed on 3 billion devices worldwide. To run Java, you would download and install the Java Runtime Environment (JRE) on your computer . JRE contains the Java Virtual Machine (JVM) and all the classes or blueprints to create objects. Java is especially useful for programmers, but is also essential for end-users who run applications with Java applets.

The Department of Homeland Security recommended everyone disable Java in January 2013 because Oracle, the company that purchased Sun Microsystems in 2009, failed to adequately address a major security issue. Russian anti-virus company Kaspersky Lab, said that half of all cyber attacks in 2012 were directly caused by Java. Most major websites, including Facebook and Twitter, use JavaScript and HTML 5 instead of Java to avoid the security risks.

Java was once considered the future of the Internet and was absolutely necessary to run just about everything after it was released. Now, most cybersecurity experts recommend uninstalling Java if you have it on your computer. If it is essential that you use Java, dedicate one browser for surfing with Java and use another one for all other Web activities.

I just got a new computer Windows 10 OS. I have FF installed and ready to go. I was just curious if I need to install Java? I had it on my old computer, but, I’m not sure if it was ever actually used. Should I install it or just wait until some application says it needs it? Thanks

Chosen solution Wait until you come across a website that tells you that you need Java. I haven’t had Java installed for a few years now, and haven’t missed it one bit. Read this answer in context 👍 4
