Finding a regular expression in java

Question

I have a String in java that is actually a JSON object. Inside the string I am trying to find a pattern matching this

"uris" : ["www.google.com", "www.yahoo.com"]

I need help in creating a pattern string to find a match for this. I have no idea of automata theory and regular expressions.

Note: the above substring will always start at "uris" and end at "]" but there can be any number of spaces in between.

Answer 1

You may use the following regex :

"uris".*?\]

see regex demo / explanation

Java ( demo )

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

class RegEx {
    public static void main(String[] args) {
        String s = "\"uris\" : [\"www.google.com\", \"www.yahoo.com\"]";
        String r = "\"uris\".*?\\]";
        Pattern p = Pattern.compile(r);
        Matcher m = p.matcher(s);
        while (m.find()) {
            System.out.println(m.group()); //"uris" : ["www.google.com", "www.yahoo.com"]
        }
    }
}
