Help with text input from user

[dense prairie]

So my post got closed because it said it's an assignment but i thought we are allowed to get HELP just not answers and if we are making an effort????

This is my code from the previous question:

public class Question2 {

        public static void main(String[] args) {

            Scanner in = new Scanner(System.in);

            while(in.hasNext()) {
                int num1 = in.nextInt();
                String character = in.next();
                int num2 = in.nextInt();
                int sum = 0;

                switch (character) {
                    case "+":
                        sum = num1 + num2;
                        System.out.println(sum);
                        break;

                    case "-":
                        sum = num1 - num2;
                        System.out.println(sum);
                        break;

                    case "x":
                        sum = num1 * num2;
                        System.out.println(sum);
                        break;

                    case "/":
                        double sumD = (double)num1 / (double) num2;
                        System.out.println(sumD);
                        break;

                    default:
                        System.out.println("unknown operator");
                        break;

                }
            }

        }

    }```

I just want help with being pointed in the right direction. I did the previous question and just need to figure out how to extend it.
Thank you.

program need to handle one line or multiple lines?

[dense prairie]

well i think its one line

in the previous question we just had to deal with mathematical expressions with only 2 variables

here we need to eccommodate the variable length

so arrays need to be used ?

It says at the end of first picture, 'Test cases will only provide one expression on one line. Multiples lines do not need to be accommodated.'

what does this have to do with JavaFX?

Oh sorry
