错误：选择不包含主类型 [英] Error: Selection does not contain a main type

问题描述

我试图在一个新项目中运行一些java文件。所以我做项目，把文件放在它，我尝试运行主文件，所以我的游戏开始。

我收到一条错误，说选择不包含主要类型。

我尝试了几种方式来运行它：

• 有人说再次启动eclipse，尝试了十几次。


• 某处还有人指出要打开一个新项目，并为旧项目建立路径。

没有工作。

我很确定它必须工作，因为我几个小时前在学校跑了。我该如何让这个工作？先谢谢你！

解决方案

希望以这种方式运行主类，看屏幕截图：

如果没有，那么尝试这种方式，如果是的话请确保您要运行的课程有主要方法，例如

  public static void main（String [] args）{ //这里的一些代码
  

同样的定义。希望这将有助于您。

I am trying to run some java files in a new project. So I make the project, put the files in it and I try to run the main file so my game starts.

I get an error that says selection does not contain a main type.

I have tried several ways to run it:

• Some say to launch eclipse again, tried this a dozen times.
• Somewhere else someone pointed to open a new project and make a build path to the old project.

Didn't work either.

I am pretty sure it must work because I ran it a few hours ago at school. How do I get this working? Thank you in advance!

解决方案

Hope you are trying to run the main class in this way see screen shot:

If no then try this way and if yes then please make sure that your class you are going to run have main method i-e

public static void main(String[] args){ // some code here}

same definition. Hope this will help you.
