Is it better to put the switch to some method of Calc class or is it ok in the main method?

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
Calc calc = new Calc();
System.out.println("Welcome\nAdd first number:");
int a = sc.nextInt();
Systen.out.println("Niw the second number");
int b = sc.nextInt();
calc.getNumbers(a,b);
System.out.printl("What would you like to do?\n1=+\n2=-\n3=÷\n4=×");
int op = sc.nextInt();
switch (op){ //Is it OK to put this switch in to main method, or should i create a new method for this in the Calc class?
case (1):
System.out.println(calc.sum());
break;
case (2): System.out.println(calc.minus());
break;
case(3): System.out.println(calc.div());
break;
case(4) : System.out.println(calc.mul());
break;
default:
System.out.println("wrong option");
}}
}

class Calc {
private int a;
private int b;

public void getNumbers(int a, int b) {
this.a=a;
this.b=b;
}

public int sum(){
return a+b;
}

public int minus(){
return a-b;
}

public int div(){
if (b>0) return a/b;
else System.out.println("you cant divide by zero");
return 0;
}

public int mul(){
return a*b;
}
}

Answer 1

1. the getNumbers should be setNumbers instead
2. create a new method for the switch in the Calc class to reduce cluttering your main Program class.

Answer 2

I think it's good as you did... "Program" is like a menu and I prefer this.
