I am using Regex API to filter some text. I want to find the following pattern:
*-*.html
A dash has to appear in the file name.

Code:

String patternStr = "[A-Za-z0-9]*.html";
Pattern pattern = Pattern.compile(patternStr);	
String str1;
        while ((str1 = in.readLine()) != null) {
			Matcher matcher = pattern.matcher(str1);

			while(matcher.find())
			{
				int start = matcher.start();
				int end = matcher.end();
				System.out.println(str1.subSequence(start, end));
			}

I don't know how to include dash (-) in the pattern string.
