I'm keep getting this part wrong. Please explain me what I did wrong and the corrections.

Part above and below are in separate classes.

/**

* Returns sum of the even numbers between 0 and the specified value,

* inclusive.

* @param number upper bound

* @return sum of the even numbers between 0 and number

*/

public int sumOfEvens(int number) {

int count = 0;

int sum = 0;

while(count >= 0 && count <= number) {

count ++;

if(number % 2 == 0) {

sum += number;

}

}

while(count <= 0 && count >= number) {

if(number % 2 == -0) {

sum += number;

}

return sum;

}

return count;

}
