爪哇 - 在数组转换字符串翻番 [英] Java - converting String in array to double

问题描述

我坚持这个pretty愚蠢的事情;

I'm stuck with this pretty silly thing;

我有这样一个文本文件;

I got a textfile like this;

您好:: 140.0 ::再见

Hello::140.0::Bye

我用其切分为一个字符串数组;

I split it into a string array using;

LS = line.split("::");

然后我尝试包含数字数组值转换为双，这样的;

Then I try to convert the array values containing the number to a double, like this;

Double number = Double.parseDouble(LS[1]);

不过，我得到以下错误消息;

But I get the following error message;

异常线程main
  java.lang.ArrayIndexOutOfBoundsException：
  1

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1

有没有人有任何想法，为什么不起作用？

Does anyone have any idea why this doesn't work?

推荐答案

我认为这是与读取文件有问题。你尝试拆分后印刷生产线和LS也的内容？

I think it's a problem with reading the file. Did you try printing line and also the contents of LS after splitting?
