Ok so this is a really easy question but I just havent used hashtables before. I have been looking at documentation and I am alittle confused. I have a bunch of data stored in a hashtable. Now I want to go through that data element by element and get it out of the hashtable. I know that I have to use the hashtable get() method however I am not really sure how to do this because the part with the keys kind of confuses me. I was trying to go through it simply like an array but it did not work. Can someone kind of give me a hand on how to go through the hashtable with keys?
