Javac actually executes the command but does not output the execution result because you do not output the execution result.
If you execute runtime.getruntime.exe c ("cmd ");
No results
Because it is not executed in a java program but on the Operating System
In this example, runtime.getruntime.exe c ("cmd/c start javac ");
You can see a command line window.
