Answer 1

Eclipse needs to see a main method in one of your project's source files in order to determine what kind of project it is so that it can offer the proper run options:

public static void main(String[] args)

Without that method signature (or with a malformed version of that method signature), the Run As menu item will not present any run options.

Answer 2

When you create a new class file, try to mark the check box near

public static void main(String[] args) {

this will help you to fix the problem.

Answer 3

Have you checked if:

1. You created a class file under src folder in your JAVA project?(not file)
2. Did you name your class as the same name of your class file?

I am a newbie who try to run a helloworld example and just got the same error as yours, and these work for me.

Answer 4

click on the project that you want to run on the left side in package explorer and then click the Run button.

Answer 5

Make sure the "m" in main() is lowercase this would also cause java not to see your main method, I've done that several times unfortunately.

Answer 6

It happens when sometimes we copy or import the project from somewhere. The source folder is a big thing to concern about.

One simple technique is, create a new project, inside the source folder, create a new class and paste the content over there.

It will work...

Hope it helps.
