How to get week numbers of a certain month?
<p>I just wanna ask what is the efficient way to get the week numbers of a certain month. I have a function with month number &amp; year as arguments, the return value of the function should be a int array which contain the week numbers of the specific month.(like following...)</p>

<pre><code>public int[] getWeeksOfMonth(int month, int year){
            //what's the efficient way to implement this??
}
</code></pre>
