如何将具有多个分隔符的String解析为long

Question

I need to parse String value into Long . Problem is, that value is separated by dots, so they are once groupingSeparator and once decimalSeparator. So 50.000 should be parsed to 50 , but 5.000.000 need to be parsed to 5000 . I've tried with DecimalFormat , but i cannot set it properly, and ended up with parsing 5.000.000 into 5 since dots were treated as decimalSeparator always.

Answer 1

String number = "5.000.000";
        String substring = number.substring(0, number.lastIndexOf("."));
        System.out.println(Long.parseLong(substring.replaceAll("\\.","")));
