Simple regex for words after another in java

I need a regex that give me word after another word. For example: 

street address Maria and another st. lohberg and give me another av. darrwerg and another st example

the desired output would be:

maria,lohberg,darrwerd,example

Maybye if there was a regex that could solve this situation: address: herman poortstrat this is text but not address give me: herman poortstrat But it is more complicated than that in my opinion. I have the following regex: (?<=\bstreet\s)(\w+) But it gives me only address after street with whitespace. My regex give me text after "street" so it could be one of solutions but i need more words like: "av.","av","av ","address"and other combinations. Generally I want to get from text only the street name and nothing else. Not the street and its number only the street. I'm not good in regex yet, so i'm asking for your help.

You need to use

\b(?:street\s+address|(?:av|st)\b\.?)\s*(\w+)

See the regex demo

Details

  • \b - word boundary
  • (?:street\s+address|(?:av|st)\b\.?) - a non-capturing group matching
    • street\s+address - street, 1+ whitespaces, address
    • | - or
    • (?:av|st)\b\.? - av or st as whole words followed with an optional dot
  • \s* - 0 or more whitespaces
  • (\w+) - Group 1: one or more word chars

Java demo:

String s = "street address Maria and another st. lohberg and give me another av. darrwerg and another st example";
Pattern p = Pattern.compile("\\b(?:street\\s+address|(?:av|st)\\b\\.?)\\s*(\\w+)", Pattern.CASE_INSENSITIVE);
Matcher m = p.matcher(s);
while (m.find()){
    System.out.println("Value: " + m.group(1));
}

Results:

Value: Maria
Value: lohberg
Value: darrwerg
Value: example

This will give you the words after address, st. or av. You can tweak it for you needs

public static void main(String[] args) {
    String str = "street address Santa Maria and another st. lohberg and give me another av. darrwerg and another st street";
    Pattern p = Pattern.compile("((address|st\\.|av\\.)\\s)(\\w+?\\s)");
    Matcher m = p.matcher(str);
    List<String> streets = new ArrayList<String>();
    while (m.find()) {
        streets.add(m.group(3));
    }
    System.out.println(streets);
}
