Why does java stream program takes more time than the nested for loop?

Question

I was solving the below question on leetcode:

You are given an m x n integer grid accounts where accounts[i][j] is the amount of money the i​​​​​​​​​​​th​​​​ customer has in the j​​​​​​​​​​​th​​​​ bank. Return the wealth that the richest customer has.

I submitted the below 2 solutions. First using streams java 8 and the other one using normal nested for loops. Time taken for each of these was 2ms and 0 ms respectively. Does anyone know why this performance overhead?

public int maximumWealth(int[][] accounts) {
    int maxWealth = 0;
    for (int[] customer : accounts) {
        int temp = Arrays.stream(customer)
                .sum();
        maxWealth = Math.max(temp, maxWealth);
    }
    return maxWealth;
}

public int maximumWealth(int[][] accounts) {
    int maxWealth = Integer.MIN_VALUE;
    for (int i = 0; i < accounts.length; i++) {
        int temp = 0;
        for (int j = 0; j < accounts[i].length; j++) {
            temp += accounts[i][j];
        }
        maxWealth = maxWealth < temp ? temp : maxWealth;
    }
    return maxWealth;
}

TIA.
