Java is a popular programming language that allows you run programs on many platforms, including Fedora.If you want to create Java programs, you need to install a JDK (Java Development Kit).If you want to run a Java program, you can do that on a JVM (Java Virtual Machine), which is provided with the JRE (Java Runtime Environment).If in doubt, install the JDK because this is sometimes required even if the intention is not to write Java programs.
Many flavors of Java exist and also many versions of each flavor.If you want to just run a specific application, check the documentation of that software to see what versions of Java are supported or have been tested.Most Java applications run on one of the following:

the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler. Now a single launcher is used for both development and deployment. The old deployment launcher, jre, no longer comes with Sun JDK, and instead it has been replaced by this new java loader.
The JDK also comes with a complete Java Runtime Environment, usually called a private runtime, due to the fact that it is separated from the "regular" JRE and has extra contents. It consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries only useful to developers, such as the internationalization libraries and the IDL libraries.

NOTE: The Intel Integrated chipset that is found on many notebook, netbook, and other machines has trouble trying to run Alice. Some higher-end Vista machines have also had difficulties. Decreasing hardware acceleration or decreasing color resolution (from 32 bit to 16 bit) has sometimes been helpful. See also the note below on updating video drivers.
We recommend using the .deb installer for the Pi. It will check the system and install java and the required libraries for you and it will add Alice 3 to the general launch menu under development. Follow the directions above to add Java to the Pi. Depending on Pi version follow these additional steps.
For the Raspberry Pi 4 you may need to add an additional library (if you used the .deb installer we will have done this for you). If this is not working correctly you will notice it via certain models including the person builder not functioning (we are working on the best way to integrate this).
Chromebooks with a native Linux Development Environment can run Alice 3. Many schools will not allow students to access the Linux Development Environment and enable GPU Support needed to run Alice 3.
A frequent cause of problems encountered when attempting to run Alice are out-of-date video drivers. This is recognizable when a red-screen occurs in the scene view or the run-time window when the Run button is clicked. See the following link for instructions on updating the video drivers of your machine. Updating Video Drivers

In many cases the majority of the interface has been translated and the difference is due to new gallery assets being added after the localization.

This tutorial will show you how to install Java on current versions of RPM-based Linux distributions: Red Hat Enterprise Linux, CentOS, Fedora, and Rocky Linux. Java is a popular programming language and software platform that allows you to run many server-side applications.
This tutorial covers installing the latest, default version of Java, as well as cherry-picking any older versions for installation, and switching between multiple versions in your environment as needed.
There are three different editions of the Java Platform: Standard Edition (SE), Enterprise Edition (EE), and Micro Edition (ME). This tutorial is focused on Java SE (Java Platform, Standard Edition). Almost all open source Java software is designed to run with Java SE.
There are two different Java SE packages that can be installed: the Java Runtime Environment (JRE) and the Java Development Kit (JDK). JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. The JDK includes the JRE as well as other software that is required for writing, developing, and compiling Java applications and applets.
There are also two different implementations of Java: OpenJDK and Oracle Java. Both implementations are based largely on the same code but OpenJDK, the reference implementation of Java, is fully open source while Oracle Java contains some proprietary code. Most Java applications will work fine with either but you should use whichever implementation your software calls for.
You may install various versions and releases of Java on a single system, but most people only need one installation. With that in mind, try to only install the version of Java that you need to run or develop your application(s).
By default, trying to install java without specifying a version will resolve to the most common stable version of the OpenJDK JRE. As you can see from this output, as of this writing, that is java-1.8.0-openjdk:
Multiple dependencies will also be provided along with Java. At the confirmation prompt, enter y then press Enter to continue with the installation. You may also be prompted to accept signing keys for the repositories you are installing from:
Note: Most of the time, command-line arguments are preceded by one dash for single-letter arguments, or two dashes for full-word arguments. Java follows a different convention of using one dash for all arguments, in this case, -version.
The interactions between Java naming conventions and Linux package naming conventions can be somewhat confusing. Earlier in this tutorial, we clarified the difference between the full JDK environment for development, and the JRE environment for running Java applications. Although OpenJDK is the name of the open source distribution of Java, you have only actually installed the OpenJDK JRE. In order to install the full OpenJDK JDK, you should install the corresponding package with -devel appended onto its name. This is a common convention for development packages for other programming environments, which Java also follows, although the terminology overlaps awkwardly here.
More recently, OpenJDK changed its version numbering scheme to track more closely with Oracle Java releases. In order to install a newer version of OpenJDK, you can specify the version number in the package name, just like with 1.8.0. For example, in order to install OpenJDK 17, you can yum install java-17-openjdk:
As before, you can install the full JDK environment by appending -devel to the package name. However, after this, running java programs will still use the OpenJDK 1.8.0 version that you installed earlier by default, which you can confirm by running java -version again:
If you installed multiple versions of Java, you may want to set one as your default (i.e. the one that will run when a user runs the java command). Additionally, some applications require certain environment variables to be set to locate which installation of Java to use.
Enter the a selection number to choose which java executable should be used by default. It will rearrange the necessary symbolic links on your system to ensure that the java command points to the correct set of libraries. You can re-run this command as needed, and the output of java -version should change accordingly:
If you want JAVA_HOME to be set for every user on the system by default, add the previous line to the /etc/environment file. You can append it to the file using echo and >> shell redirection, in order to avoid having to edit the /etc/environment file directly, by running this command:
Throughout this section we will be using the wget command to download the Oracle Java software packages. wget may not be included by default on your Linux distribution, so in order to follow along you will need to install it by running:
Note: In order to install Oracle Java, you will need to go to the Oracle Java Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux x86 .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
In this tutorial, you installed and managed multiple versions of Java using the yum package manager, the alternatives command, and environment variables. These are all fundamental aspects of Linux environment management, and Java provides an especially good example of working with them because of its many different versions.
