As long as the JButton (or any Component for that matter) isn't visible it doesn't have a size or position ...

kind regards,

It is visible, when I run it I can see the frame with jbuttons.

In my main method:

public static void main(String[]args){

MyButtonDemo btnDemo = MyButtonDemo();
btnDemo.setDefaultCloseOperation(EXIT_ON_CLOSE);
btnDemo.setBounds(0,0,350,350);
btnDemo.setVisible();
}

It is visible

Not when you sysout the size in your first code, it isn't.

Why do you think you need to know the size of the button?

The JButton has an image inside it, I want the "image to be resize larger if the gui has been maximized or resize smaller if the gui has been minimized" to be exactly fit inside the JButton.

Get the size of the button after calling pack() on the parent JFrame, or making the JFrame visible - which will layout your components using the LayoutManagers and allow you to get the initial size.
