Can I repeat the lines here after they are declared?

I am trying to use PowerShell for a small code generation task. I want the script to generate some java classes and interfaces.

In the script, I want to declare a string variable here. For instance:

$controllerContent = @"
package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Controller
@EnableWebMvc
public class $completeName {

}
"@

After the declaration, I want to pass it to the function where I compute the variable $completeName. But I do not know how to replace the variable in my line correctly. Do I need to use -replace? Or is there some other way?
