java冒牌排序? 400 报错

第二步，应该是fj=fi######第二个for循环括号里面的条件写错了######

谢谢各位

将你的代码稍加修改如下：

publicclassMaoPaoPaiXu{publicstaticvoidmain(String[]args){int[]fl={59,60,4,5,1};for(inti=0;i<fl.length-1;i++){for(intj=i;j<fl.length-2;j++){if(fl[j+1]>fl[j]){inttemp=fl[j+1];fl[j+1]=fl[j];fl[j]=temp;}}}for(inti=0;i<fl.length;i++){System.out.print(fl[i]+"");}}}

输出：60 59 5 4 1

下面介绍一个冒泡排序的代码。它考虑的比较全面，请仔细学习。

importjava.util.Arrays;importjava.util.Random;publicclassBubbleSort{staticvoidbubble_sort(inta[]){//起泡排序方法，将数组排序，排成递减序列inti,j,t,n=a.length;booleanswap=true;intcount=1;/*如果，某趟循环后，布尔变量swap仍然为false，则说明此趟循环，*未发生过交换。这意味着，数组已经有序，即排序操作已经完成，排序应终止。因此，布尔变量swap为true,是外层循环的一个必要条件。/for(i=n-1;i>0&&swap;--i){/每次外层循环，先设布尔变量swap为false，说明尚未发生交换/swap=false;/*Thebooleanflagremainsfalseduringthelastbobblerun,*implyingthatnoswapoccurredandthewholearrayiscompletelysorted.Inthiscaseoneshouldterminatethebubblesortprocessimmediately./for(j=0;j<i;++j)//i为外层循环的控制变量，在此用作内循环的上限。/*外层循环的控制变量i每次完成一趟循环后，递减1。用它作内循环的上限，可以终止在稳定区内做不必要的比较。//*Weusei,whichhasone_decreaseaftereachouter_forloop,astheupperlimitfortheinner_looptoavoidtheunnecessarycomparisonsmadeofthestableregion.Thestableregionisthearraysegementabovetheindexi./if(a[j]<a[j+1]){//若后边的元素比前边的大，即为逆序/则将两个记录交换/t=a[j];a[j]=a[j+1];a[j+1]=t;swap=true;/布尔变量值swap为true说明,在这一趟起泡排序中，至少发生过一次交换。//thebooleanflagistrueimplyingthatatleastaswapoccurredduringthisbobblerun/}System.out.print("The"+count+++"run:");System.out.println(Arrays.toString(a));}}publicstaticvoidmain(String[]args){int[]array=newint[15];Randomrand=newRandom();for(inti=0;i<array.length;i++)array[i]=rand.nextInt(120);System.out.print("Theoriginal:");System.out.println(Arrays.toString(array));bubble_sort(array);}}

输出：

冒牌排序，你是要假冒伪劣的排序算法吗？
