在java中解析货币字符串 [英] Parsing a currency String in java

问题描述

假设我提供的字符串类似于$ 123,456,56.25或123'456.67或类似的东西（带有数字和小数点以及某些分隔符，如，或'或其他类似的东西是不可预测的）。我需要编写一个方法，它接受类似上面的参数并返回一个字符串，如12345656.25或123456.67分别。

Suppose I'm supplied with a String which is like "$123,456,56.25" or "123'456.67" or something similar to this (with digits and a decimal point and some seperator like , or ' or something else which is not predictable). I need to write a method which takes an argument like the one above and returns a String like "12345656.25" or "123456.67" respectively.

你能否提出最有效和最易读的代码来实现这个目标？

Could you please suggest the most efficient and readable code to achieve this?

注意：我知道要检查每个索引并检查其重新定位器 true 是否为 Character.isDigit（charAtInedx）或 if（charAtInedx =='。'）
我正在寻找一个在效率和可读性方面更优化的解决方案

Note: I'm aware of going through each indexes and checking for whether its retunrs true for Character.isDigit(charAtInedx) or if(charAtInedx == '.') I'm looking for a more optimized solution both in terms of efficiency and readability

谢谢。

推荐答案

String newStr = oldStr.replaceAll("[^\\d.]+", "")

这将删除任何字符这不是数字或期间

This will drop any character that is not either a digit or a period
