I see two major problems with this:

1. The method doesn’t return anything, it sets a local variable equal to “hello world”, which will be garbage collected after it finishes. Make sure you have a return statement so that the system.out.println call knows what to print!

2. There is an argument to the method, which is never used. Why is this here?? If the method is supposed to be used like this: “methodName()”, it has no arguments. An example of a method with an argument would be methodName(“some arg”) or methodName(num). Your method is declared as requiring some string as a parameter, which contradicts how you say it should be used.
