冒泡排序Java数组应用

Java冒泡排序代码示例：

int [] arr={2,4,3,6,5,1,9,8};

          for ( int i=0;i length -1;i++){

              for ( int j=0;j length -i-1;j++){

                  int temp=0;

                  if (arr[j]>arr[j+1]){   //升序排列大于号，降序排列小于号

                      temp=arr[j+1];

                      arr[j+1]=arr[j];

                      arr[j]=temp;

                 }

             }

         }

         System. out .println(Arrays. toString (arr));
