请教一个堆栈排序的问题，JAVA

[清晨v]

毕业多年，数据结构忘记的差不多，下面的排序算法一直调试不出来，请高手！

public class HeapSort_a {
	private static void adjust(int H[], int s, int length) {
		int tmp = H[s];
		int child = 2 * s + 1;
		while (child < length) {
			if (child + 1 < length && H[child] < H[child + 1]) {
				++child;
			}
			if (H[s] < H[child]) {
				H[s] = H[child];
				s = child;
				child = 2 * s + 1;
			} else {
				break;
			}
			H[s] = tmp;
		}
	}

	private static void build(int H[], int length) {
		for (int i = (length - 1) / 2; i > 0; i--) {
			adjust(H, i, length);
		}
	}

	public static void sort(int H[], int length) {
		if (H.length > 0) {
			build(H, length);
			for (int i = length - 1; i >= 0; --i) {
				int tmp = H[i];
				H[i] = H[0];
				H[0] = tmp;
				adjust(H, 0, i);
			}
		}

	}
	
	public static void main(String[] args)
	{
		int[] A = {1,3,4};
		
		HeapSort_a.sort(A,A.length);
		for(int i = 0;i<A.length;i++)
		{
			System.out.println(A[i]);
		}
		
	}
	
}
