Mixing
Creating an instance of each class when choosing it's tab (JTabbedPane)
Project Screenshot
I have multiple tabs, each tab refers to a class, what I need is to create an instance of the class when the specific tab is pressed.
Is there any way to do that?

When you want to read only when the group tab is opened and detect when the selected tab changes you need add ChangeListener and get its index:
getJTabbedPane().addChangeListener((ChangeEvent e) -> {
switch (tabPane.getSelectedIndex()) {
case 0:
//do something
break;
case 1:
//do something
break;
default:
break;
}
});
Instead of index you can use also selected component if your group tab implemented as custom class:
getJTabbedPane().getSelectedComponent() instanceof <CustomPanel.class>
