Why doesn't this code work? Throws ArrayIndexOutOfBoundsException. Really weird, what am i missing?

        String s = "java.awt.Color.r.0.g.255.b.0.";
        String[] split = s.split(".");        
        System.out.println(split[0]);

It happens because String.Split() expects a regular expression pattern string as a parameter, And in regular expressions, the "." is a special character, so to tell regular expressions that you want to match the exact "." you just add an escape character so it looks like "\." But still won't work because you need another escape character for java (1 for regex and 1 for java string) so all you need is to replace s.split(".") with s.split("\\.").

        String s = "java.awt.Color.r.0.g.255.b.0.";
        String[] split = s.split("\\."); //regex delimiter        
        System.out.println(split[0]);
