And what is your question or problem in it?

[jackhammer]

its for a car sales business scenario where people can pick the model type, engine size etc...

and then i want all the prices to add up at the end!! we're not suppose to use GUI!!

the code i posted has errors but i cant figure them out!!

[Supamagier]

Use this after the prices are given...

totalPrice = carValue + gasPrice + transmissionPrice + enginePrice;

Instead of before.

Can you post your error message and ask your question more clearly?

System.out.println("What size of an engine do you want? 1, 1.2, 1.4, or 2 litre");

int engineSize = scan.nextInt();



switch (engineSize) {
case 1: System.out.println(1);
enginePrice = 50;
break;
case 2: System.out.println(1.2);
enginePrice = 100;
break;
case 3: System.out.println(1.4);
enginePrice = 150;
break;
case 4: System.out.println(2);
enginePrice = 200;
break;
default: System.out.println("Invalid Engine Size");
break;
}

System.out.println("Your car is " + totalPrice);
}
}

in this set of statements you declared the engineSize variable as an int. but gave the user non whole number choices (1.2, 1.4) if u enter this the code is only going to read 1 and the first case statement will execute. changing the data type to float will fix that.
