Can someone show me a more simple way to do this?

Question about the task

Under discussion

I just need to know a simpler way to do the code. I did a basic System.out.println(1 + 2); add on the next number 5 times and got the solution correct. But I know that I am doing more work than needed. Please explain how to use a better way. I read about loops? can someone explain?

Some of the other suggestions might be a little cleaner, but I figured I'd share my loop as well. I think we'll learn a little more about these later, but I gleaned a little info just from examples used earlier in the course.

public class Solution {
    public static void main(String[] args) {
        //write your code here
        int ans = 0;
        int count = 1;
        while(count < 6) {
            ans = ans + count;
            System.out.println(ans);
            count = count + 1;
        }
    }
}

Hail to the people that want to do less work than needed! Write a for loop: int sum = 0; for (int i = 1; i <= 5; i++) { sum = sum + i; System.out.println(sum); } Make sure you place the {} in the correct place, otherwise your will get errors. Good luck!

Bro, only for you , I did all the hard work only for you ! System.out.println(1); System.out.println(3); System.out.println(6); System.out.println(10); System.out.println(15); and surprisingly enough this works! to your astonishment !

You can do this by using a loop. in main method you can write the following code int sum = 0; for(int i = 1; i <= 5; i++){ sum = sum+i; System.out.println(sum); }

useful

Yes a for loop is what you're looking for, will be explained in few lessons later. Even later, you might as well do it using a collection.
