Java – for Windows 7, what is runtime getruntime(). Exec (“domain specific equivalent CLS”)

I want to clear the screen in my java application. After reading a lot of questions and Google search, I found the following code

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

or

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

But the above code does not work in Windows 7 I know the "CLS" script is domain specific. Who knows what text I should use in Windows 7 This will be very useful, thank you in advance

Solution

I realize that you are looking for an easy way to clear the screen You will have to use line feed hackers or
