J jackshow Unregistered / Unconfirmed GUEST, unregistred user! 2003-07-10 #4 用正则表达式 public class Demo { public static void main(String[] args) { String str = "001#002# "; Pattern p = Pattern.compile( "001"); Matcher m = p.matcher( str ); boolean pt = m.matches(); if (pt = true) { System.out.println("find the 001"); } } }
