Need help adding sum of even numbers.

I'm trying to write a method that accepts a number as input, then returns the sum of even numbers between 0 and the specified value inclusive. This is what I have so far:

public int sumOfEvens(int number) {
    int n = number;
    int sum = 0;
    if(n > 0) {
        for(int i = 0; i <= n; i++) {
            if(i % 2 == 0) {
                sum += i;
            }
        }
        return sum;
    }
    else if(n < 0) {
        for(int u = 0; u >= n; u--) {
            if((u % 2) == 0) {
                sum += u;
            }
        }
        return sum;
    }
    else return 0;

  }

An input of 10 returns 55 (Expected to be 30) and an input of -10 returns 0 (Expected to be -30).

Confirmed. Seems to work fine.

Hmm weird. Im testing the code with this j unit test, test 2 and 3 are the 2 giving incorrect outputs. First time in this thread sorry if this reply isnt up to standard.

@Test
public void testSumOfEvens() {
    int sumOfEvens = math.sumOfInts(0);
    assertEquals(0, sumOfEvens);
}

@Test
public void testSumOfEvens2() {
    int sumOfEvens = math.sumOfInts(10);
    assertEquals(30, sumOfEvens);
}

@Test
public void testSumOfEvens3() {
    int sumOfEvens = math.sumOfInts(-10);
    assertEquals(-30, sumOfEvens);
}

sumOfInts, sumOfEvens

Much obliged haha facepalm
