Java Simple Calculator (JSC)

The following is my first assignment in learning Java programming, only the output display has been determined by the supervisor, so what can I do, I can't improvise.

Java Simple Calculator

Case study

With Java, create a simple calculator program, accompanied by screenshots!

Example screenshot:

Kalkulator Sederhana
(bill operator bil2) > 4 x 5
hasilnya = 20
(bill operator bil2)
// jika kosong maka program selesai
Terimakasih

        }
        System.out.println(total);

Output
