Thread: Can't get the loop to work properly

*****Solved it myself, thanks for help*****



Hey there,
I've got a program which I need to test whether an integer n is the exact sum of k consecutive integer numbers starting from 1.
eg. 6 is 1 + 2 + 3 and therefore k = 3 and if I put in 4 then it returns false. But what I've only able to achieve so far is to get the program to add numbers 1 to n together, so if I enter 6 I get 21 because 1 + 2 + 3 + 4 + 5 + 6 = 21, but this isn't what I need the program to do. :/ I'm kinda stuck, I've tried a few other things but they aren't working.

import java.util.Scanner;
public class ExactSum {
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Scanner keyboard = new Scanner(System.in);
		System.out.println("Type an integer:");
	    int n = keyboard.nextInt();
 
	    System.out.println("The number "+n+" is not an exact sum");
	    } 
	      else {System.out.println("The number "+n+" is the sum of integers from 1 to "+k+" ");
              }
 
	    }
	}

Any help is appreciated!
