How to find all double quote substrings in a string with Java

Answer 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.util.ArrayList;

public class ExtractSubstrings {
    public static void main(String[] args) {
        String str = "This is a string with \"double-quoted substring1\", and \"double-quoted substring2\" inside.";

        // Regular expression pattern to match substrings within double quotes
        String pattern = "\"([^\"]*)\"";

        // Compile pattern and create matcher
        Pattern compiledPattern = Pattern.compile(pattern);
        Matcher matcher = compiledPattern.matcher(str);

        // List to store extracted substrings
        ArrayList<String> substrings = new ArrayList<>();

        // Find all matches
        while (matcher.find()) {
            substrings.add(matcher.group(1));
        }

        System.out.println(substrings);
    }
}
