私のコードに問題があります。BorderLayout/GridBagLayout（Java）で位置が間違っています
私がそれを起動すると、2つのパネルが重なっていても、1つのパネルを北と1つを南に宣言しました。
EingabePanelが一番上にあり、SchnittpunktPanelが一番下にあると考えられます。
ここにコードがあります。多分誰かが私を助けることができます。 GUIで作業しているのは初めてです。

に問題が 'BorderLayout'ではありませんが、 'GridBagLayout' –

EingabePanelが一番上にあり、SchnittpunktePanelが停止していると考えられます。しかし彼らは上の両方にある – MasterSansai
