想問(wèn)一下萬(wàn)能的網(wǎng)友，這下面的是不是冒泡排序，按理說(shuō)第一次排序會(huì)把99放到最后面的啊，可是為什么這個(gè)99被它吃了？吃了也就算了，居然還沒(méi)有排序
public class Main {
?????public static void main(String[] args) {
??????????int[] arr = {99,44,77,33,55,88,66};
??????????? for(int y = 0; y < arr.length; y++){
??????????????? if(arr[y] > arr[y+1]){
??????????????????? int temp = arr[y];
??????????????????? arr[y] = arr[y+1];
??????????????????? arr[y+1] = temp;
??????????????? }
??????????????????? System.out.print(arr[y]+",");
??????????? }
????}
}

for循環(huán)里，到y(tǒng)=6的時(shí)候，此時(shí)arr[6]=99，但arr[y+1]超過(guò)此數(shù)組的范圍了。你把a(bǔ)rr[6]和arr[y+1]交換，自然arr[6]會(huì)不見(jiàn)了。
