How to send cmd variables to java main function using eclipse

Question

I have a java program that is supposed to take an file name from the cmd. My main function looks like this:

public static void main(String[] args) {
        try {
            solve(args);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

The args is a file name that I send it to the function solve. I am using eclipse. I went to Run menu and then, Run Configuration, and I pasted the file path in the Arguments tab for both the Program arguments and the Vm arguments. When I run my program using eclipse, I get the following error:

Error: Could not find or load main class C:\MyFolder\MyFile

Please remove it from VM parameters, then all will be fine

You just need program arguments.

You should not add it to the VM arguments. Only to the Program arguments. VM arguments are arguments passed... to the VM. Like memory options, system properties, etc.

If the file path contains any spaces, you have to enclose the parameter in double quotes.

Remove it from VM arguments, program arguments belong to the argumennts box.

VM arguments are arguments to java itselv, e.g. set maximum heap memory to 128MBytes: -Xmx128m

java interprets plain vm arguments as the main class it should execute.
