Intellij无法运行hello world[关闭]

Question

这是代码（我正在研究IntellijJava）：我不知道是什么导致了它。

package Scratches;

public class scratch {
    public static void main(String[] args) {
        System.out.println("hello world!");
    }
}

这是控制台：

Answer 1

可能你把IDE搞砸了。您的问题的答案可能是：

无法解析文件C：\用户\Ran_Durbach1\ideaProjects\learnjava\learnjava.iml： prolog中意外的字符'c'（代码99）

检查这个文件。
