new to matchres

hi all ,

i have a list of Strings

List<String> list = new ArrayList<String>();

		list.add("A_01_B");
		list.add("A_02_B");
		list.add("A_03_B");
		
		list.add("A_01_C");
		list.add("A_02_C");

and a method

public static String fillExpected(String expected, List<String> list){}

fillExpected method should return "A_04_B" when passed ""A_XX_B" as expected String.(Incrementing the value of the int at the positions of XX , considering A and B matching combinations).
and should return "A_03_C" when passed ""A_XX_C" as expected String.

this can be achieved by matchers and wild cards right?
any suggestions please.

Pattern p=Pattern.compile("A_[0-9]+_B");

Matcher m=p.matcher(searchString);

if(m.matches())
{
    String match=m.group();
    String ret=match.subString(2,match.length()-3);
    int x=Integer.parseInt(ret);
    return "A_+ret+"_B";    
}
