if you are just starting learning Java and dont understand whats going on with all that stuff with eclipse, I would recommend you to start from the basics, write your code in an ordinary text editor (notepad will do, or notepad++ if you want something more), after you have written and saved your source file, open up your command prompt, navigate to the location of the file, and run:
如果您刚开始学习 Java 并且不了解 Eclipse 的所有内容，我建议您从基础开始，在普通文本编辑器中编写代码（记事本可以，或者记事本++，如果您想要更多的话） )，在编写并保存源文件后，打开命令提示符，导航到文件所在的位置，然后运行：
javac YourFileName.java
java YourFileName

There is no problem with learning Java with Eclipse or any other IDE. If you move file from one computer to the other you need as it was said start a new project or you can use existing project and import files. In order to import files right click on a project and click then Import and select files. Then you should be able to run your class. Also be sure to have the Java perspective selected when you work on your class.
使用 Eclipse 或任何其他 IDE 学习 Java 没有问题。如果您将文件从一台计算机移动到另一台计算机，则需要启动一个新项目，或者您可以使用现有项目并导入文件。为了导入文件，右键单击一个项目，然后单击“导入”并选择文件。然后你应该能够运行你的类。还请确保在您处理类时选择 Java 透视图。
