Java - Clearing screen clears printed text after its execution

Question

Inside of method

new ProcessBuilder("cmd", "/c", "cls").inheritIO().start();

System.out.println("Press enter to continue...");

Back to main method Switch

System.out.println("Blah blah blah");

In both cases my program clears everything, leaving no text to tell the user what to do, but instead a blank terminal. I've also tried creating its own method, but it will still clear text before and after its execution.

You need to wait for the external process to finish. You can do that with Process.waitFor(). Like,

Process p = new ProcessBuilder("cmd", "/c", "cls").inheritIO().start();
p.waitFor(); // <-- wait for p to finish

For people with similar future problems, use the answer from above, then put throws IOException, InterruptedException from the method it is called and every method higher up.

Instead of posting a new answer that is the same as the answer suggested 11 hours ago, you should accept that answer. – Jason Armstrong Dec 04 '18 at 16:40
