get closest value to a number in array
<p>I have an array of positive/negative ints</p>

<pre><code>int[] numbers = new int[10];
numbers[0] = 100;
numbers[1] = -34200;
numbers[2] = 3040;
numbers[3] = 400433;
numbers[4] = 500;
numbers[5] = -100;
numbers[6] = -200;
numbers[7] = 532;
numbers[8] = 6584;
numbers[9] = -945;
</code></pre>

<p>Now, I would like to test another int against this array, and return the number that is closest to the int.</p>

<p>For example if I used the number <code>490</code> i would get back item #4 from numbers <code>500</code> what is the best way to do something like this?</p>

<pre><code>int myNumber = 490;
int distance = 0;
int idx = 0;
for(int c = 0; c &lt; numbers.length; c++){
    int cdistance = numbers[c] - myNumber;
    if(cdistance &lt; distance){
        idx = c;
        distance = cdistance;
    }
}
int theNumber = numbers[idx];
</code></pre>

<p>That doesn't work. Any suggestions on a good method to do this?</p>
