Problem basic calculator

#1

import java.util.;
public class Main {
public static void main(String args[]) {
Scanner cin = new Scanner(System.in);
char c = cin.nextLine().charAt(0);
while(c != ‘x’|| c != ‘X’){
int n1 = cin.nextInt(), n2 = cin.nextInt();
switch©{
case '’ :
System.out.println(n1*n2);
break;
case ‘/’ :
System.out.println(n1/n2);
break;
case ‘+’ :
System.out.println(n1+n2);
break;
case ‘-’ :
System.out.println(n1-n2);
default:
System.out.println(“Invalid operation. Try again”);
}
c = cin.nextLine().charAt(0);
}
}
}== what’s the error

#2

pls change the scn.nextLine to scn.next()
and 2nd mistake is
when c==‘x’
ur code is taking n1 and n2 from user
but there is no input

so pls correct it
otherwise the approach is fine

hope this will help u
