正则表达式解析街道名称

Question

I have the following code that I would like to use to capture street names from an address string.

For an address of "77 ELM ST", the code below gives me "ELM" which is correct.

For an address of "115 GEORGE APPLETON FOX ST" the code gives "APPLETON". The expected result should be " GEORGE APPLETON FOX"

For example:

private static String ADDRESS_PATTERN = "^\\d*\\s*(\\w+\\s*)*ST$";

public String parseStreet(String address) {
    Pattern addressPattern = Pattern.compile(ADDRESS_PATTERN);
    Matcher matcher = addressPattern.matcher(address);
    boolean found = matcher.find();
    return found ? matcher.group(1).trim() : null;
}

What am I doing wrong?

Answer 1

Put the capturing groups around the submatch you want to capture. For example:

"^\\d*\\s*((?:\\w+\\s*)*)ST$"
