So far I have this:
package CashRegister;
import java.util.Scanner;
public class CashRegister {
public static void main(String[] args) {
Scanner askPrice = new Scanner(System.in);
for(double i = 0 ; i < 3; i++);
{
System.out.println("Enter a value") ;
double price = askPrice.nextDouble();
}
}
}
How can I prompt the user for three values and add them together?
seems like a homework . So just a hint here. Try to learn and do by yourself with the help
To calculate the sum you need to declare a variable out of the for loop scope. so declare a variable say sum and after each input add price to sum. After the end of loop the sum will containt the result.
Edit:
we all missed a minor thing.. You placed a semicolon (;) after for loop remove this..
so use
for(double i = 0 ; i < 3; i++)
instead of
for(double i = 0 ; i < 3; i++);
As you have used semicolon the for loop has a blank statement. So your input is not in the scope of for loop.
Take a look at this example I built on your code:
double[] price= new double[3];
for (int i=0; i<3; i++) {
System.out.println("Enter another ");
double price[i] = askPrice.nextDouble();
}
Later on, you can iterator over the price array, and add all the values:
double total = 0.0;
for (int i=0; i<price.length; i++) {
total += price[i];
}
