这个报错怎么解决。。。
Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: D:\eclipse-workspace\Testone\bin
Caused by: java.lang.module.InvalidModuleDescriptorException: Test.class found in top-level directory (unnamed package not allowed in module)

你的包呢

直接将报错信息复制粘贴到百度就好啦，看看别人怎么解决

遇到同样问题~新建一个包，右击包新建一个类即可

It seems that you haven't created a package. My usual procedure in Eclipse is:
•Create new Java project
•Inside that project: Create a new package
•Inside that package: Create a new Java class
Eclipse will help you a lot with the settings. Then just copy your code into that class and hit the 'start' button.

没包
