Answer 1

Your code and regular expression is valid. You don't need to include the .* at the beginning and the end of your regex. For example:

String t = "hsw.ads hsw.ads hsw.ads";
int count = 0;
Matcher m  = Pattern.compile("hsw\\.ads").matcher(t);
while (m.find()){ count++; }

In this case, count is 3. And another thing, if you're going to use a regex, if you REALLY want to specifically look for a '.' period between hsw and ads, you need to escape it.
