代码：

public class BucketSort {
    public void sortFunction(int[] array, int bucketNum) {
        int max = Integer.MIN_VALUE, min = Integer.MAX_VALUE;
        for (int i : array) {
            max = Math.max(max, i);
            min = Math.min(min, i);
        }
        List<List<Integer>> bucketList = new ArrayList<List<Integer>>();
        for (int i = 0; i < bucketNum; i++) {
            bucketList.add(new ArrayList<Integer>());
        }
        for (int i : array) {
            int bucketIndex = (i - min) * (bucketNum - 1) / (max - min);
            List<Integer> list = bucketList.get(bucketIndex);
            list.add(i);

        }
        for (int i = 0, arrIndex = 0; i < bucketList.size(); i++) {
            List<Integer> bucket = bucketList.get(i);
            Collections.sort(bucket);
            for (int num : bucket) {
                array[arrIndex++] = num;
            }
        }

    }
}
