    Default regular expressions

    ok straight to the problem, i have this String that my program reads from a file:

    package javaapplication1;
     
    public class Main {
     
        public static void main(String[] args) {
          String example = "0001Brad Lambert        00000200.0008081987blambert@my.wctc.edu";
          int tmpa,tmpb;
          String tmp;
          String nameexp = "[A-Z][a-zA-Z]{3,} [A-Z][a-zA-Z]{3,}";
     
               tmpa = example.indexOf(nameexp);
                tmpb = example.lastIndexOf(nameexp);
                System.out.println(tmpa);
                System.out.println(tmpb);
                tmp = example.substring(tmpa, tmpb);
                System.out.println(tmp);
        }
     
    }
    im trying to use a regular expression
    to pulll out the name "Brad Lambert" to a temporary string value
    problem is tmpa and tmpb keep returning a value of -1.

    To get better help sooner, post a SSCCE* that clearly demonstrates the problem and what you've done so far. Without that, members here would be simply guessing.

    Default Re: regular expressions

    indexOf does not use regular expressions. See Lesson: Regular Expressions (The Java™ Tutorials > Essential Classes) for information on how to use regular expressions in java. Alternatively you could go the messy way and split the string, get the flanking strings and their indexes to rebuild the string found with the regex.
