Is there a way to pass user inputs several times in java in SoloLearn's code playground?

Answer 1

It's not possible to input something while the code is running, that's a problem of the playground.

Answer 2

Scanner scanner = new Scanner (System.in);
int i1 = scanner.nextInt();
int i2 = scanner.nextInt();
int i3 = scanner.nextInt();

then put every input like this:
1
2
3
