java list addall 报错啊 表示看不懂问题在哪
求大牛解答 真心感谢 两个类型是一样的啊 添加不进去急死了
this.little1.remove(j);
j--;//避免下标越界
你这个代码贴的 我都看不出来 既然报错了，
1.看看什么错误，贴出来错误
2.你的l[i].shot()类型和你enemyBullets的类型是不是一致？
看看shot方法，的debug追踪下
我感觉问题出在remove上，一定是越界了。
shot方法返回的是一个集合，集合里面的元素是Bullet1类型，而你的enemyBullets集合里的泛型不知道是什么类型(在你的代码里没看到)，如果不是Bullet1类型的话就会报错(因为当你调用addAll方法是，是把shot方法返回的集合里的元素加到enemyBullets集合里去，如果这两个集合里的元素的泛型类型不一致的话就会报错)，希望对你有帮助

下面发了部分源码 太大了 求各位大能帮帮忙啊
直接一个工程地址还好点
