The Virtual Machine is built right into your software download and helps run Java apps. The Virtual Machine is only one aspect of software that is involved in web interaction. I have heard the terms Virtual Machine and JVM. The Plug-in software is not a standalone program and cannot be installed separately. The JRE allows applets written in the programming language to run inside various web browsers. The JRE is the runtime portion of the software, which is all you need to run it in your Web browser. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. The Java Runtime Environment (JRE) is what you get when you download software. What will I get when I download software?
Installing this free update will ensure that your applications continue to run safely and efficiently. The latest version contains important enhancements to improve the performance, stability, and security of the applications that run on your machine.
Why should I upgrade to the latest version? It's the platform for launching careers, exploring human-to-digital interfaces, architecting the world's best applications, and unlocking innovation everywhere-from garages to global organizations. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere! Itis at the heart of the digital lifestyle. The program is fast, secure, and reliable. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Itis a programming language and computing platform first released by Sun Microsystems in 1995. Many cross-platform applications also require Java to operate properly. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which Enables Applets to Run in Popular Browsers and Web Start, which deploys standalone applications over a network. It provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. It's also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing. This is all intended as constructive criticism, I appreciate the effort you put into it, I just dont want anyone to come to grief because of it.Java Runtime Environment (JRE) allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. mozilla/plugins folder will be used and by who, I had a look around and firefox has a couple of plugins directories but not there, and will this work for multiple users or just me? And there is simply not enough information there to know how the. I have a non standard location for my downloads even though I fixed it so that it still looks like it is under my home directory so when i did your step 5 I got a mass of errors that quickly zipped off the screen and if I hadnt noticed them would have left my Java folder short of a couple of hundred of the most important files, I looked in the folder and it had lots of stuff there so thought maybe they had been warnings went and had a look it was a permission thing I went back to step 5 and added sudo to the beginning of your first line and it went thru.Īlso in your final Optinal(sic) step you have mispelled mozilla - not sure if thats an issue actually but makes me a bit suspicious that you didnt actually run those commands - just typed them here. The instructions are a bit terse, there is plenty of room for stuff to go wrong,
Optinaly install firefox plugin by linking libnpjp2.so file to ~/.mozzila/plugins folder.

Mint comes with a OpenJDK version of java libraries, which shouldn't be used for example Android development.
Tutorial about How to install JRE for Linux Mint is almost identical for JDK. Unlinke JRE, Java Development Kit includes various development tools like the Java source compilers, bundling and deployment tools, debuggers, development libraries, etc.
