I’m running a large Java Eclipse project and when it starts up, I see 3 pop-up windows tiled on top of each other, as so:

I need to have them start up separated positions, as I’m always testing the program and dragging the windows. Can I somehow put them all in a bigger GUI window(pane)?
Use setLocation() method
passing the ‘null’ as an argument will make the window center.
There is another way,
method. this will locate them according to the existing things like JLabels, existing windows, etc.
