It's my first question here so please be patient :-)
I try to code very simple Java game. First I want to generate a sample task like "2+2 = ". Than use user must answer what is the result. Next I want to generate a char and other random number.

> 
> 2 +2 = (4) if answer == result, than generate random char nad number
>  4 - 1 = (3) if answer == result, than generate random char nad number
>  3 + 5 = (9)
> 
> 
> 

Currently I am stuck with the character generation.

```
import java.util.Random;

public class Main {
    public static void main(String[] args) {
        Random randomNumber = new Random();
        int userRandomNumber = randomNumber.nextInt(10) - 1;
        int myRandomNumber = randomNumber.nextInt(10) - 1;
        int i = giveResult(userRandomNumber, myRandomNumber);
        System.out.println(userRandomNumber);
        System.out.println(myRandomNumber);
        System.out.println(i);

    }

    public static int giveResult(int userRandomNumber, int myRandomNumber) {

        Random randomNumber2 = new Random();
        int switchRandomNumber = randomNumber2.nextInt(2);
        char operatorRandom = '+';
        int result = 0;

        switch (switchRandomNumber) {
            case 1:
                operatorRandom = '+';
                result = userRandomNumber + myRandomNumber;
                //return result;
                break;
            case 2:
                operatorRandom = '-';
                result = userRandomNumber - myRandomNumber;
                //return result;
                break;
            default:
                result = 0;

        }
        return result;
    }
}

```

How to correct my code and what next steps do?
