Removing Dollar and comma from string

Question

How can we remove dollar sign ($) and all comma(,) from same string? Would it be better to avoid regex?

String liveprice = \"$123,456.78\";

Answer 1

In my case, @Prabhakaran's answer did not work, someone can try this.

String salary = employee.getEmpSalary().replaceAll("[^\\d.]", "");
Float empSalary = Float.parseFloat(salary);

Answer 2

import java.text.NumberFormat

def currencyAmount = 9876543.21 //Default is BigDecimal
def currencyFormatter = NumberFormat.getInstance( Locale.US )

assert currencyFormatter.format( currencyAmount ) == "9,876,543.21"

Don't need getCurrencyInstance() if currency is not required.

Answer 3

Example using Swedish Krona currency

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);

Will give the output ->19823567.10(which can now be used for any computation)

Answer 4

Is a replace really what you need?

public void test() {
  String s = "$123,456.78";
  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.

Answer 5

Without regex, you can try this:

String output = "$123,456.78".replace("$", "").replace(",", "");
