java 冒泡排序和字串倒敘輸出

好久沒寫了，論壇看到了，寫一下

int[] array = {1,8,6,3,8,45,62,21,100,98};for(int i = 0;i<array.length;i++){int a = array[i];int k=i;for(int j=i+1;j<array.length;j++){if(array[i]<array[j]){//int temp =array[i];//array[i] =array[j];//array[j] = temp;兩種不同的調換順序array[i] +=array[j];array[j] =array[i]-array[j];array[i] = array[i]-array[j];}}}for(int i = 0;i<array.length;i++){System.out.print(array[i]+",");}

 字串倒敘輸出

String str="abc減肥減肥";StringBuffer stringBuffer = new StringBuffer (str);    System.out.print(stringBuffer.reverse());
