Eclipse "Run as" has no "Java Application" option (What exactly is needed to be able to run a class/.java?)

I want to run a specific .java file (a class), but Eclipse is not co-operating.

I have tried to follow the instructions here --> eclipse how to run a different class

... but my "Run As" menu item never contains "Java Project".

I have tried accessing the menu after right-clicking in the .java pane and tab itself, and from the .java name and class name in the Package Explorer, but of course that doesn't make a difference. The only option I ever get is "Run Configurations".

(and yes, my .java has a "main" method.)

import com.jsyn.JSyn;

public class SuperSimpleSounds {

    public static void main() {

[...]

What, exactly, is needed to be able to run an individual class (an individual .java file)?

As a minor variation on the perfect answer of Reimus:

Add a String array argument to the main method as expected by the JVM

public static void main(String[] args) {

I had been struggling with my a script, when I ran it showed Run Configuration and Fail.
By changing the following: 

public static void LaunchBrowser () throws InterruptedException {

to 

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

it solved the problem.

Also one trick when you want to open some java classes that you downloaded elsewhere is to create a new Java project. Then, move all your java classes into the src folder of the project. Now you can run with the option of "run as Java Application".
