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