Simple beginner questions about Apex classes
Hi All,
I'm new to Apex programming and I ran into some problems and I hoped one of you could advise.
I'm trying to follow this article on how to call a visual cloud flow from Apex:
https://andyinthecloud.com/2014/10/26/calling-flow-from-apex/
I followed the instructions on the Hello World Example, I created a simple flow, opened the developer console and pasted the following:
It worked great.
Then I wanted to create a new Apex class to store it.
I created a new Class and pasted the following:
But got this error message:
Error: Compile Error: Method must define a body at line 6 column 1
So here's my first question, why did it work on the Developer console without defining the method first?
Anyways, I added the method and here's the complete code:
But the error persists!
What am I doing wrong? Clearly I'm missing something very obvious.
Thank you.

@Barracks : To facilitate the development of robust, error-free code, developer Console supports the creation and execution of unit tests. Unit tests are class methods that verify whether a particular piece of code is working properly.
In Apex method is more of a synonym for function . Try this code
start() is a predefined method . If you use that name for your own custom method , then Salesforce Apex engine will be confused , so do not use the standard method names .Let me know if any more issues come .
