多くの追加パラメータを入力するために、1つのメインJFrameと1つの追加JFrameがあります。だから、私は2番目のjframeがメインのjframeにデータを返す必要がある( "Save"ボタンのActionListenerを使う)が、どうすればいいのか分からない。してください、私に助けてくれることを願ってください。ありがとうございました。モーダルJFrameまたは別のJComponentを作成するには?

2番目の従属ウィンドウをJFrameにしないでください。代わりにモーダルJDialogまたはJOptionPaneを使用してください。 JOptionPaneがGUIを保持するJPanelをJOptionPaneに配置するだけで、JOptionPanesが複雑なGUIを保持できることは多くの人が気づいていません。例えば

import java.awt.*; 
import java.awt.event.*; 
import java.util.HashMap; 
import java.util.Map; 

import javax.swing.*;
