windowbuilderを使用して3つのGUIフレームを作成し、この順序でロードおよび表示します。
- 1番目のGUI（Home.java）
- 2番目のGUIと3番目のGUI（Results1.java、Results2.java）
明らかに、Home.javaを最初にロードできますが、後続の2つのGUIはHome.javaと同時にロードされます。GUIの要素を初期化するメソッド内に印刷構文を挿入したので、それを確認できます。Home.javaのボタンを押した後、最後の2つのGUIを表示できますが、コンテンツはすでにロードされています。したがって、これら2つのGUIに変数を渡す必要がある場合、値はnullになります。何か案は？
Home.Javaボタンが押されました。
