Regex to extract the main class in java source code

Question

I have a multi-class java file. One of those classes contains a main method (public static void main...). Example:

class one {...}
class two {...}
class three {
   public static void main(String[] args) {...}
}

I tried

class.*?[^.*?]*?main

but that matches starting at class one not class three

Given the complexity of Java syntax, a regex is not really suited for this. — Andreas

\s*static\s*void\s*main\s*\(\s*String\s*\[\]\s*[^\)]*\)

if you want the name of class you can test this regex

class\s*([^\{]*)\{\s*.*static\s*void\s*main\s*\(\s*String\s*\[\]\s*[^\)]*\).*
