Thread: 'for' loop problem

i need to create a progam that enters even integers until the input number is reached. for some reason i think my for statement(for (int i = 2; i < x; i+= 2)) is messed up because it returns 18 intstead of 20 when 10 is entered. ive played around with this program to try to get it to work for several hours and i just can't find the solution. any pointers?

import java.util.Scanner;
public class EvenSum {
 
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		double x, sum = 0;
		System.out.println("Enter number: ");
		x = scan.nextInt();
 
		for (int i = 2; i < x; i+= 2){ 
			sum = i + x;		
	}
 
		if(x < 2){
			System.out.println("Cannot enter number less than 2.");
			System.exit(0);}
 
		System.out.println("Sum of all evens is: " + sum);
	}
}

thanks in advance

you got it
