using jsp, i have a servlet that queries a database and returns all of the database tables in a pipe delimited string.

my question is this: is there a way to split the string into an array (similar to the split method in javascript), or is there an easy way to iterate through the resultset in the servlet and return an array instead of a string.

is there a better way to do this alltogether? i'm open to suggestions.

if there are multiple answers that i adopt, i will add additional questions and/or increase the points.

Yes, you can use the StringTokenizer class. This will pewrmit you to iterate through the string and parse out the contents based on the delimiter that your provide.


The following is one example of the use of the tokenizer. The code:

     StringTokenizer st = new StringTokenizer("this is a test");
     while (st.hasMoreTokens()) {
         println(st.nextToken());
     }
 
prints the following output:

     this
     is
     a
     test
 

Constructor Summary
StringTokenizer(String str)
          Constructs a string tokenizer for the specified string.
StringTokenizer(String str, String delim)
          Constructs a string tokenizer for the specified string.
StringTokenizer(String str, String delim, boolean returnDelims)
          Constructs a string tokenizer for the specified string.
