jGRASP问题;我不能运行程序？ [英] jGRASP problem; I can't run a program?

问题描述

我尝试运行此代码：

I tried running this code:

public class HelloWorld {

public static void main(String[] args) {
System.out.println("Hello, World");
}

}

我点击了编译文件按钮，没有出现任何问题，但当我点击运行当前文件的应用程序按钮时，我得到一个弹出窗口，上面写着：以下文件缺少类或内部类文件：C：\ Users \Larry \Downloads \ HelloWorld.java不建议在纠正之前继续进行。我该怎么办？

I clicked the "compile file" button and no problems appeared, but when I clicked on the "run application for current file" button, I got a pop-up that said: "The following file is missing class or inner class files: "C:\Users\Larry\Downloads\HelloWorld.java" Proceeding before correcting is not recommended." What should I do?

推荐答案

除了少数例外，Java期望一个类包含在一个与该类名称完全相同的文件中。对于您在此处描述的代码（public class HelloWorld（...）），编译器希望它位于文件HelloWorld.java中。我怀疑情况并非如此......

With few exceptions, Java expects a class to be contained in a file with exactly the same name as the class. For the code you describe here ("public class HelloWorld(...)"), the compiler wants it to be in a file HelloWorld.java. I suspect that is not the case...
