如何INT []转换成列表＆LT;整数GT;在Java中？
问题描述：
如何转换 INT [] 到列表＆LT;整数GT; 中的Java
How do I convert int[] into List<Integer> in Java?
当然，我感兴趣的任何其他答案不是项目做一个循环中，项。但是，如果没有其他的答案，我会挑选一个作为最佳显示的事实，这个功能不是Java的一部分。
Of course, I'm interested in any other answer than doing it in a loop, item by item. But if there's no other answer, I'll pick that one as the best to show the fact that this functionality is not part of Java.

有没有捷径从 INT [] 转换为列表＆LT;整数GT ; 为 Arrays.asList 不涉及拳击，只是创建一个列表＆LT; INT []＆GT; 这是不是你想要的。你必须做出一个实用的方法。
There is no shortcut for converting from int[] to List<Integer> as Arrays.asList does not deal with boxing and will just create a List<int[]> which is not what you want. You have to make a utility method.
int[] ints = {1, 2, 3};
List<Integer> intList = new ArrayList<Integer>();
for (int index = 0; index < ints.length; index++)
{
intList.add(ints[index]);
}
