Is there a Class(es) in java for Pre-baked sorting Algorithm code?
<p><strong>I was searching for class that implemented algorithms.. i found some code online...</strong></p>

<pre><code>package sun.misc;

public class Sort {

    private static void swap(Object arr[], int i, int j) {
    Object tmp;

    tmp = arr[i];
    arr[i] = arr[j];
    arr[j] = tmp;
    }

    /**
     * quicksort the array of objects.
     *
     * @param arr[] - an array of objects
     * @param left - the start index - from where to begin sorting
     * @param right - the last index.
     * @param comp - an object that implemnts the Compare interface to resolve thecomparison.
     */
    public static void quicksort(Object arr[], int left, int right, Compare comp) {
    int i, last;

    if (left &gt;= right) { /* do nothing if array contains fewer than two */
        return;          /* two elements */
    }
    swap(arr, left, (left+right) / 2);
    last = left;
    for (i = left+1; i &lt;= right; i++) {
        if (comp.doCompare(arr[i], arr[left]) &lt; 0) {
        swap(arr, ++last, i);
        }
    }
    swap(arr, left, last);
    quicksort(arr, left, last-1, comp);
    quicksort(arr, last+1, right, comp);
    }

    public static void quicksort(Object arr[], Compare comp) {
        quicksort(arr, 0, arr.length-1, comp);
    }
}
</code></pre>

<p>Now i am wondering if there are some specific classes for the most commonly algorithms like bubble sort / heap sort / binary tree etc in java ... Do you guys have any idea?</p>
