NetBeans中找不到主类 [英] No Main class found in NetBeans

问题描述

我一直在为我的班级编程工作。我正在使用NetBeans。我完成了我的项目并且工作正常。当我尝试运行它时，我收到一条消息没有找到主要类。以下是一些主要的代码：

I have been working on an assignment for my class in programming. I am working with NetBeans. I finished my project and it worked fine. I am getting a message that says "No main class found" when I try to run it. Here is some of the code with the main:

package luisrp3;
import java.io.FileNotFoundException;
import java.io.PrintStream;

public class LuisRp3 {

public static void main(String[] args) throws FileNotFoundException  {

    java.io.File newFile = new java.io.File("LuisRamosp4.txt");

    if (newFile.exists()) {
        newFile.delete();
    }

    System.setOut(new PrintStream(newFile));

    Guitar guitar = new Guitar(); 

我之前发布了这个，但有几个问题。我已经修复了其他人，现在剩下这一个了。任何建议将不胜感激。

I posted this before but had a couple issues. i have fixed the others and now have just this one remaining. Any advice will be greatly appreciated.
