Java(Apex) RegEx not working?

I am having trouble with a regex in salesforce, apex. As I saw that apex is using the same syntax and logic as apex, I aimed this at java developers also. I debugged the String and it is correct. street equals 'str 3 B'.

When using http://www.regexr.com/, the regex works('\d \w$').

The code:

Matcher hasString = Pattern.compile('\\d \\w$').matcher(street);
    if(hasString.matches())

My problem is, that hasString.matches() resolves to false. Can anyone tell me if I did something somewhere wrong? I tried to use it without the $, with difference casing, etc. and I just can't get it to work.

Thanks in advance!

You need to use find instead of matches for partial input match as matches attempts to match complete input text.

Matcher hasString = Pattern.compile("\\d \\w$").matcher(street);
if(hasString.find()) {
   // matched
   System.out.println("Start position: " + hasString.start());
}
