Java Regex to get JSON schema

Question

I need to get a JSON object from a String

in this string the JSON content is unique with this form:

abit2:{....};

I made my regex this way, but I'm unable to stop at semicolon

public String getJSON(String content) throws MalformedURLException, IOException{

    String json = "";       

    String regex = "abit2:([\\s\\S]*)\\};"; 
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(content);     
    while (matcher.find()) {            
        json = matcher.group().replace("abit2:", "");       
    }

    return json;        
}

Don't do this. There are some well known JSON parser libraries in Java. — anubhava

You forget to include the opening curly brace and you need to make this [\\s\\S]* pattern as non-greedy.

String regex = "abit2:\\{([\\s\\S]*?)\\};";
