Regex Example for Currency Symbols

In this Java regex tutorial, we will learn to match all available currency symbols, e.g. $ Dollar, € Euro, ¥ Yen, in some text content or a String in Java.

1. Regex for Currency Symbols

In regular expressions, the property\Sc represents the currency symbols. We can use the \\p{Sc}to match all currency symbols in the string.

\\p{Sc}

Note that \p{Sc} is PCRE regex property and Javascript doesn’t support it.


\p{Sc} is PCRE regex property and Javascript doesn’t support it. In Javascript you need to use specific symbols in character class to match them like this:

/[$£]/

2. Example

In the following program, we have a test string that contains the 3 currency symbols. We will use the above-discussed regular expression to match the currency symbols, and then print their locations in the string.

String content = "Let's find the symbols or currencies : $ Dollar, € Euro, ¥ Yen"; String regex = "\\p{Sc}"; Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); Matcher matcher = pattern.matcher(content); while (matcher.find()) { System.out.print("Start index: " + matcher.start()); System.out.print(" End index: " + matcher.end() + " "); System.out.println(" : " + matcher.group()); }

The program output:

Start index: 39 End index: 40 : $ Start index: 49 End index: 50 : € Start index: 57 End index: 58 : ¥
