You will need to go to Project->Clean...,then build your project. This will work, even when your source code does not contain any main method to run as an executable program. The .class files will appear in the bin folder of your project, in your workspace.
您需要转到Project->Clean...，然后构建您的项目。即使您的源代码不包含任何作为可执行程序运行的 main 方法，这也将起作用。.class 文件将出现在您项目的 bin 文件夹中，在您的工作区中。

In the case that you delete your .class file in Eclipse and then try to build it again from the .java file it will do nothing. If you try to run the .java file without the .class file you will get an error that it can not find the main class.
如果您在 Eclipse 中删除 .class 文件，然后尝试从 .java 文件再次构建它，它将什么也不做。如果您尝试在没有 .class 文件的情况下运行 .java 文件，您将收到一个错误，指出它找不到主类。
You will either have to change and re-save the .java file then build it again, or else you have to run Clean on the project then build again.
您要么必须更改并重新保存 .java 文件，然后再次构建它，要么您必须在项目上运行 Clean 然后再次构建。
