Why you mention split string ? If using split() to split string with delimiter
of "-",for example, the code will be this

String string = "004-034556";
String[] parts = string.split("-");
String part1 = parts[0]; // 004
String part2 = parts[1]; // 0

Could you write it more and in detail

You can't really handle nesting well with regular expressions. What you're doing is dealing with a mini-language so you need to create a parser for it

If you want
add(add(12,5),5)  to change to  No((no(12)+no(5))+no(5))      
import java.util.regex.*;
public class Test {
   public static void main(String args[]){
    String s = "add(add(12,5),5)";
	Pattern p = Pattern.compile("-?\\d+");
        Matcher m = p.matcher(s);
	StringBuilder sb = new StringBuilder("No((");
	while (m.find()) {
		sb.append("no(" + m.group() + ")+");
	}
	sb.deleteCharAt(sb.length() - 1);
	sb.append(")");
    System.out.print(sb.toString());
   }
}

I suspect your example is a sample representation of some real data that probably has more than one variation. Perhaps you can provide some different samples and, most importantly, an explicit explanation of the criteria to employ to produce your desired results.
