Can someone please help me find what is wrong with my code below. The program is suppose to add all the input numbers except for the sentinel which is -1. What am i doing wrong?
public class InClassWork
static Scanner console = new Scanner(System.in);
public static void main (String args)
int total = 0;
number = console.nextInt();
total = total + number;
while (number != -1);
System.out.println("The sum of the numbers entered is " + total);
You add the number you enter to the total before the while checks if its value is -1.
you should start number at 0 like you do for total, and switch both lines in your do-while, this way, on the first run through it will add 0 to the total. and on everyother pass its gonna add the last number before asking a new one.
To be a little more logical, you should use a while loop instead and ask for 1 number input BEFORE the while loop, then in the loop add the number THEN ask a new one. But both loops will work that way.
well you dont need the do while statement, the while statement will do the job correctly-verifying the variable before executing, where as the do while verfiys the value at the end of each execution. also incorporate the 'number = console.nextInt()' into your while statement that should fix it :)
