The term Project in Eclipse can refer to a standalone project, or to a project “module” that has dependency or parency with some other projects in the IDE. In Eclipse, you can simultaneously work on multiple Projects. The workspace location is often the default directory when creating new projects, but this can always be changed. Your projects and code can either be stored in the workspace location or in another directory. The state of your IDE (directories visible as projects, preferences, workbench arrangement, etc.) is stored in the workspace location. When starting the IDE, you’re prompted to select a workspace. In this case, installation only requires extracting the archive and running the executable. Alternatively, you can download one package dedicated to your use case directly. The installer will guide you through installation. There is a generic installer, which is recommended. To make sure you’re ready, just type `java -version` in a terminal, and see that a recent version (>= 1.8.0) is installed and that the target architecture (x86, x86_64…) matches your computer and OS. The only prerequisite for installation is to have a Java Virtual Machine installed (such as OpenJDK or Oracle JVM).
