some questions

DataSet ds = runSQL(sql);

if (ds.getRowCount() > 0) {

String stddev = ds.getString(0, "stddev");

System.out.println("0000" +stddev);

This is just a small peice of my code any ideas what the 3rd line is doing I know it is setting stddev equal to a string from ds which is a dataset item but I don't get the arguments of the getstring function.

any help would be great.

Check the API javadocs for the DataSet class. It's not part of Java SE or Java EE, so it's up to you to research this.~

ok I think I got that figured outthanks I work at a large company that is doing oracle DB connected to webbased query and dataentry programs and they are working with lots of different hashmaps. Is there a way to view all the hashmaps ever created?

Ever created? No! :-)

Do you mean all the hashmaps currently in existence inside your application? Only if your code adds a reference to each hashmap to some sort of collection, but enforcing that that happens could be tricky
