JAVA 冒泡排序 public class Example32 {public static void main (String[] ags){int []arr={9,8,3,5,2};System.out.print("冒泡排序前：");printArray(arr);bubbleSort(arr);System.out.println("冒泡排序后：");printArray(arr);}public static void printArray (int []arr){for(int i=0;i<arr.length;i++){System.out.print(arr[i]+" ");//数字后面加一个空格}System.out.print("n");}public static void bubbleSort (int []arr){for(int i=0;i<arr.length-1;i++){for(int j=0;j<arr.length-i-1;j++){if(arr[i]>arr[i+1]){int temp=arr[j];arr[j]=arr[j+1];arr[j+1]=temp;}}System.out.printf("第"+(i+1)+"轮排序后：");printArray(arr);}}}
运行结果如下：
