JAVA数组的快速排序

package test;

public class ArrayTest {
	
	//交换数组元素
	private static void swop(int[] array ,int low,int high) {
		
		int temp=array[low];
		array[low]=array[high];
		array[high]=temp;
	}

	//快速排序方法
	private static void arrayRank(int[] array,int lowIndex,int highIndex) {
		int low=lowIndex;
		int high=highIndex;
		int temp;
		if(lowIndexlowIndex)&&(array[high]>temp)) {
					--high;
				}
				if(low<=high) {
					swop(array, low, high);
					++low;
					--high;
				}
			}
			if(lowlowIndex) {
				arrayRank(array, lowIndex, high);
			}
		}
		
	}
	
	
	public static void main(String[] args) {
		
		int [] array= {9,5,7,4,20,2,6,8};
		arrayRank(array, 0, array.length-1);
		for (int i : array) {
		System.out.println(i);
	}
