Regex to find word starting with $ symbol.

Question

Hi,
I want to find all the words in a JTextPane starting with "$" symbol followed by alphabets or digits.
Below is the code, which I have written
public void matchAllWords(String textPaneData) {
     String regexStr =  "\\b(\\$?(\\w+))\\b";
     Pattern p = Pattern.compile(regexStr);
     Matcher m = p.matcher(textPaneData);
     while (m.find()) {
           System.out.println(m.group());
}Suppose the text pane data is
hello $world 2$ $test_string $50.0 $5*5
I want the method to match the following words
$world
$test_string
$50.0
But the program is printing:
hello
world
2
test_string
50.0
5*5
Please help me, where am I going wrong.
Thanks in advance.
Regards,
Vaishakh

How To Ask Questions The Smart Way

Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal - in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.
