I'm new to swing I have been reading about the flow and border and I'm quite sure I know how they work.
But well I can't figure out one thing, when I put FlowLayout with let's say 5 buttons inside border layout as the north panel and what I'm trying to do is when I resize the window I want the buttons to not dissappear but instead show in new line, it is working with just FlowLayout but inside border when I have something under the north panel the buttons are just hidden.
I have been trying to do this using PreferredLayoutSize.
The thing I would like to know, where do I have to put the dimension from PreferredLayoutSize to make it work?

Why do you want flow layout at all? Inside border layout the components will shrink as the whole display is shrunk. A flow layout needs to retain enough area to display all its cotained components, otherwise they fall off the end and disappear.
Try a 5×1 grid layout instead, or a horizontal box layout.
