This is incorrect. The parameter "myResult" will be filled locally on line 3 but that value will never make it back to the caller via "myResult", only by the return of the method. So, just remove "myResult" from this method and you'd be good to go.
This is still uses "myResult". Instead, just send back the results of num1*num2;
Like this...
While it's not a hard and fast rule,
Java programmers have come to think of methods that begin with 'get....' as a "getter" used to access the fields of your class. Your method "getResult" would be easier to read if it was renamed "calcResult".
