Question

I am rather new at java, and I know this cant be too difficult, but I cant quite figure it out.

String xxChange = request.getParameter("XXChange");     
String yyChange = request.getParameter("YYChange");    
String zzChange = request.getParameter("ZZChange");  
String aaaChange = request.getParameter("AAChange");  

So basically I am getting these parameters and just setting them to strings. Each one of these strings has multiple numbers then two letters after it, and my question is how do I remove the letters and set it to a new string. Fyi….the number in front of the letters is on a sequence, and could grow from being 1 digit to multiple, so i dont think i can do string.Substring.

Answer 1

You want to remove the last two characters, so use substring like this:

String s = "123AB";
String numbers = s.substring(0, s.length() - 2);
