What did i do wrong
Java Code:import java.util.*; public class Summer { public static void main (String[] args) { Scanner in = new Scanner(System.in); int first = 0; int last = 0; int total = 0; int i = 0; System.out.println("Hello. I will calculate the sum"); System.out.println("of consecutive integers."); System.out.println("Please enter the starting number:"); first = in.nextInt(); System.out.println("Please enter the ending number:"); last = in.nextInt(); while (last < first) { System.out.println(last + " is smaller than " + first); System.out.println("The ending number must be bigger than the first"); System.out.println("Enter the starting number again"); first = in.nextInt(); System.out.println("Enter the ending number again"); last = in.nextInt(); System.out.println("The sum of the numbers are " + total); total = sum(last, first); } for (i = first; i <= last; i++) { total = total + i; } } public static int sum(int num1, int num2) { int result; result = num1 + num2; return result; } }

Actually no need to use method sum, for loop do the calculation for you.
Java Code:total =new Summer().sum(last, first);

Yes, and still no response at all here. I think he wants to find the sum of all numbers within two integers, need to validate on that second number should be greater that the first.

I think again somebody wrote the code for him and he jumps from forum to forum with the code.

Are you comes with cross-posting in another forum.

In another thread you will see that he even doesn't know about main method,look at the "i will pay" thread and you will understand.
