在Java中将StringBuilder转换为整数值 [英] Converting a StringBuilder To Integer Values In Java

问题描述

问题很简单。假设有一个 StringBuilder sb 这样的sb数字内部：

Well the question is very simple. Lets say there is a StringBuilder sb Inside of sb numbers like this:

25 9631 12 1895413 1 234564

"25 9631 12 1895413 1 234564"

如何逐个获取这些数字并将其初始化为的ArrayList<整数>列表或者更具体一点是可能的吗？感谢您的检查！

How to get those numbers one by one and initialize them into an ArrayList<Integer> list or to be more specific is it possible? Thanks for checking!

推荐答案

尝试将该字符串拆分为：

Try to split that string like:

String[] numbers = sb.toString().split(" ");//if spaces are uneven, use \\s+ instead of " "
for (String number : numbers) {
    list.add(Integer.valueOf(number));
}
