#choice for tip by user

choice=int(input("enter your choice for tip:(1 for 15%, 2 for 18% and 3 for 20% :)"))

// calculate the total food bill

if choice==1:

   tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.15)

elif choice==2:

   tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.18)

elif choice==3:

   tot_food_bill=tot_bill+tot_bill*tax+tot_bill*(.2)

else:

   print("invalid choice:")

Fiesta28 [93]
Here you go. I added a constructor and a toString overload to make the object creation and printing as easy as possible.

public class student {
    private String _id;
    private String _name;
    private String _address;

    public student(String id, String name, String address) {
        _id = id;
        _name = name;
        _address = address;
    }

    public String toString() {
        return "Id: " + _id + "\nName: " + _name + "\nAddress: "+ _address;
    }

    public static void main(String[] args) {
        student s1 = new student("S12345", "John Doe", "Some street");
        System.out.println(s1);
    }
}
