No Main class found in NetBeans

Question

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(); 

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.

Answer 1

1. Right click on your Project in the project explorer
2. Click on properties
3. Click on Run
4. Make sure your Main Class is the one you want to be the entry point. (Make sure to use the fully qualified name i.e. mypackage.MyClass)
5. Click OK.
6. Run Project :)

If you just want to run the file, right click on the class from the package explorer, and click Run File, or (Alt + R, F), or (Shift + F6)
