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

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.
