排序算法-冒泡排序

java实现，见代码：

package com.zyg.test.sort;public class BubbleSort {public static void main(String[] args) {int[] array = {10,5,7,12};System.out.print("排序前；");printArray(array);bubbleAscSort(array);bubbleDescSort(array);}/** * 冒泡升序排序 * @param array */public static void bubbleAscSort(int[] array){int length = array.length;int temp=0;for(int i=0;i<length-1;i++){for(int j=0;j<length-i-1;j++){if(array[j]>array[j+1]){temp = array[j];array[j] = array[j+1];array[j+1] = temp;}}}System.out.println();System.out.print("升序排序后；");printArray(array);}/** * 冒泡降序排序 * @param array */public static void bubbleDescSort(int[] array){int length = array.length;int temp=0;for(int i=0;i<length-1;i++){for(int j=0;j<length-i-1;j++){if(array[j]<array[j+1]){temp = array[j];array[j] = array[j+1];array[j+1] = temp;}}}System.out.println();System.out.print("降序排序后；");printArray(array);}public static void printArray(int[] array){int length = array.length;for(int i=0;i<length;i++){System.out.print(array[i]);if(i!=length-1){System.out.print(",");}}}}
