Java program which sums numbers from 1 to 100

Question

I have been recently started learning Java and would want to make code that sums the numbers from 1 to 100 (result would be 5050)

The code should go like 1+2+3+4+5+6+7+8+

Answer 1

You output the value of nmb that is the numeric value that you iterate on, you don't increment the actual value with the current sum.

You should introduce a local variable before the loop to compute and maintain the actual sum.
Besides, int nmb; could be declared directly in the loop.
Narrowing the scope of variables makes the code more robust.

public class T35{

    public static void main(String[] args) {
        int sum = 0;

        for(int i= 1; i<= 100; i++){    
            sum += i;
            System.out.println(sum);    
        }    
    }

}
