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

public class test {

public static void main(String[] args)

{

String regx = "[^a|b|3]";

String temp = "6sabcsssfsfs33";

Pattern p = Pattern.compile(regx);

Matcher m = p.matcher(temp);

while (m.find())

{

System.out.print(m.group());

}

}

}
