Shorthand lab problems...

Question

ok were doing a shorthand lab in class using only the basic string and character commands and in the lab the user inputs a string like "This is FOR YOU TO try AND convert." and the output takes out all the vowels, and it replaces the word "for" with "4", and with "&", and two with "2".....now i had absolutely no trouble taking out the vowels, it's replacing the words thats the problem, my line of code takes out "and" and replaces it with "&" but it can only do it to the first and in the sentence so if the user put in "I went and shot a duck and dog" it would only change the first and "I went & shot a duck and dog" I need it to change both...here is the code
if (n>-1)
     while (chr<n)
     char ch = str.charAt(temp+1);
     temp += 1;
     str0=str0+ch;
     chr = chr+1;     
     len = str.length();
     System.out.println(len);
     str0=str0+"&";
     chr = n+3;
     temp = n+3;
     while (chr<len)
        char ch = str.charAt(temp);
        temp += 1;
        str0 = str0+ch;
        chr = chr +1;
}

Answer 1

anything i can do about the whole hand become h& thing? so it only accepts it?Look at the regex api, and find the regex pattern to identify a word boundary
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.htmlI could give it to you, but you would be better off looking it up, and while you're there,
having a glance at the other patterns, just for future reference.
when you work it out - you have to cover before and after
