Removing Dollar and comma from string
提问by Varun Vishnoi
How can we remove dollar sign ($) and all comma(,) from same string? Would it be better to avoid regex?
我们如何从同一个字符串中删除美元符号 ($) 和所有逗号 (,)？避免使用正则表达式会更好吗？
String liveprice = "3,456.78";

Try,
尝试，
String liveprice = "3,456.78";
String newStr = liveprice.replaceAll("[$,]", "");
replaceAlluses regex, to avoid regex than try with consecutive replacemethod.
replaceAll使用正则表达式，避免使用正则表达式而不是尝试使用连续replace方法。
String liveprice = ",23,456.78";
String newStr = liveprice.replace("$", "").replace(",", "");

Just use Replaceinstead
只要使用Replace替代
String liveprice = "3,456.78";
String output = liveprice.replace("$", "");
output = output .replace(",", "");
回答by OldCurmudgeon
Is a replace really what you need?
您真的需要更换吗？
public void test() {
String s = "3,456.78";
StringBuilder t = new StringBuilder();
for ( int i = 0; i < s.length(); i++ ) {
char ch = s.charAt(i);
if ( Character.isDigit(ch)) {
t.append(ch);
}
}
}
This will work for any decorated number.
这适用于任何装饰数字。

Without regex, you can try this:
没有正则表达式，你可以试试这个：
String output = "3,456.78".replace("$", "").replace(",", "");

Example using Swedish Krona currency
使用瑞典克朗货币的示例
String x="19.823.567,10 kr";
String x="19.823.567,10 kr";
x=x.replace(".","");
x=x.replaceAll("\s+","");
x=x.replace(",", ".");
x=x.replaceAll("[^0-9 , .]", "");
System.out.println(x);
System.out.println(x);
Will give the output ->19823567.10(which can now be used for any computation)
将给出输出 ->19823567.10（现在可用于任何计算）

I think that you could use regex. For example:
我认为你可以使用正则表达式。例如：
"19.823.567,10 kr".replace(/\D/g, '')
回答by kapsid
In my case, @Prabhakaran's answer did not work, someone can try this.
就我而言，@Prabhakaran 的回答不起作用，有人可以试试这个。
String salary = employee.getEmpSalary().replaceAll("[^\d.]", "");
Float empSalary = Float.parseFloat(salary);
