Dynamically changing jTable with HashMap

I didn't write any code yet, so sorry about that but need some direction and clarification before proceeding. Can I create a dynamic link between with a JTable and Hashmap? So when ever my listenrs add something new or delete something, it will update the Hashmap and that would update the JTable, I was thinking of re-creating the JTable everytime a change happens? That is one of my buttons being pressed.

Any suggestions?

A JTable is just the visible component, the data is contained in a TableModel. Any changes inside the model will be reflected in the JTable itself. So you can create a TableModel that uses a HashMap internally.

Here's Oracle's table tutorial for more info
