Eclipse is an open source, Java-based extensible development platform. On its own, it's just a framework and set of services for building a development environment through plugin components. Fortunately, Eclipse comes with a standard set of plug-ins, including the Java Development Kit (JDK).
IDE (Integrated Development Environment): can automatically compile (save to compile), code prompts. (Eclipse can also be used as an IDE for other development languages, such as C, C++, PHP, and Ruby, etc.)
About eclipse workspace:
Multiple workspaces can be created in Eclipse, and each workspace can create multiple projects
A workspace is a set of configuration information. After the workspace is switched, the configuration of the previous workspace will not take effect.

How to run java program:
We can view it in Package Explorer
可以在 Package Explorer 视图中快速运行 Java 程序。
Package Explorer 视图:
鼠标右击包含 main 函数的 java 类选择 Run As > Java Application
同样你也可以在 Package Explorer 视图中选择包含 main 方法的类并按下快捷键： Alt + Shift + X, J
以下两种方式都能创建一个新的 Run Configuration(运行配置) 我们可以使用它来启动 Java 应用程序。
如果运行配置已经创建，你可以在 Run 菜单中选择 Run Configurations 来启动 Java应用，点击运行配置的名称，然后点击运行按钮的Java应用程序。
