What is runtime.getruntime (). exec ("domain equivalent for cls") for Windows 7

I want to clear the screen in my Java application, after reading many questions and searching on Google, I found the code below

runtime.getruntime().exec("cls")

or

Runtime.getRuntime().exec("cmd /c cls");

but the code above does not work in Windows 7. I know that the "cls" script is a domain, does anyone know what text I should use in Windows 7. It will be really useful, thanks in advance.
