class Solution {
    public int solution(int[] numbers, int n) {
        int answer = 0;
       for(int i : numbers) { answer+= i; if(answer>n){ break; } } return answer;
    }
}

 

 

 

 

 

 

 

 

import java.util.Arrays;

class Solution {
    public int solution(int[] numbers, int n) {
        return Arrays.stream(numbers).reduce(0, (acc, i) -> n >= acc ? acc + i : acc);
    }
}

 reduce !!
