在"Hello World“应用中出现"Message: Content is not allowed in trailing section”错误

Question

当我尝试运行hello world时，我一直收到以下错误代码。它显示内部错误

package com.company;

public class Main {

    public static void main(String[] args) {
    // write your code here
        System.out.println("Hello World.");
    }
}

上面是我从我的教授那里复制的代码，但它似乎适用于除我之外的所有人。生成以下我一无所知的语句

Answer 1

这是Intellij项目文件/Users/jayrobinson/IdeaProjects/Hello World/Hello World.iml的问题。代码没有任何问题。我的建议是创建一个新的intellij java项目，再次创建Main.java类文件，然后尝试运行新项目。
