The garbage collector won't free objects that have still a reference. If it does, and the hell if I know how you figure that out, it is because your code does not have any more links to these objects. Unless you show your code, there is not much we can …

ArrayList are not synchronized while Vector are. No way Vactor will become obsolete. And yes you can use Vector of Vector. JTable use them

If you do not want to use standard Java JComponent and their look and feel why using Java ?

JComboBox inside JComboBox ? Never seen that before. I have seen cascaded combobox where selecting an item in the first one will change wat the other one shows but never what you mentionned. Anxious to see your code

I'll bet your problem is somewhere else or you have a lot and lot and a lot of data in each of your pane. If it is the case, yes you can. Just add all your pane (JPanel I presume) empty Have a Listener to inform you when a Tab …

What in your terminoly is an "object name" tabbedPane.getSelectedIndex() will tell you which pane is visible

If each Tab has a JTextPane make an array of them then textPane[tabbedPane.getSelectedIndex()] will be the one in use
