Reverse an array? : <p>I'm trying to reverse an array, but I don't know how to get the correct output (4,3,2). My questions are; how do I print the output (using System.out.println())? Nothing I've tried works. My second question is; is the rest of my code correct?</p>

<pre><code>public static void main(String[] args) {
int arr[] = {2,3,4};
int i = 0;
int j = arr.length - 1;


while( i &lt; j ) {

    int temp = arr[i];
    arr[i] = arr[j];
    arr[j] = temp;


    i++;
    j--;
}
}
</code></pre>
