    Post simple basic calculator

    am trying to make a simple calculator but i really want something more than this ,here is my code :

    package revolution;

    import java.util.Scanner;


    public class simplecalculator {

    public static void main(String[] args){
    int x , y ,result = 0 ;
    char c;

    Scanner input = new Scanner(System.in);

    //gather user inputs

    System.out.print("ENTER NO.: ");
    x = input.nextInt();

    System.out.print("enter operator: ");
    String st = input.next();
    c = st.charAt(0);





    System.out.print("ENTER NO.: ");
    y = input.nextInt();


    switch(c){

    case'+':
    result = x + y;
    System.out.print("SUM: "+result);
    break;

    case'-':
    result = x - y ;
    System.out.print("DIFFERENCE: "+result);
    break;

    case '*':
    result = x*y;
    System.out.print("MULTIPLE: "+result);
    break;

    case '/':
    result = x/y;
    if(y == 0){
    System.out.print("ERRORIVISION BY ZERO");
    }else{

    System.out.print("DIVISION: "+result);

    }
    break;

    default:
    System.out.print("SYNTAX ERROR");







    }





    }




    }

    try to do the process continuously, like after the first operation, ask again the user whether he/she wants to do another operation.

    or
    create a GUI for you calculator. that would be a challenging one
