Need help debugging this assignment import java.util.*; public class DebugSeven2 { public static void main(String[] args) { String str; int x; int length; int start; int num; int lastSpace = -1; int sum = 0; String partStr; Scanner in = new Scanner(System.in); System.out.print("Enter a series of integers separated by spaces >> "); str = in.nextLine; length = str.length(); for(x = 0; x <= length; ++x) { if(str.charAt(x) == ' ') { partStr = str.substring(lastSpace + 1, y); num = Integer.parseInt(partStr); System.out.println(" " + num); sum += number; lastSpace = x; } } partStr = str.substring(lastSpace + 1, length); num = Integer.parseInt(partStr); System.out.println(" " + num); sum += num; System.out.println(" -------------------" + "\nThe sum of the integers is " + sum); } }.
