JFrameを作成し、テキストフィールドとボタンを配置しました。テキストフィールドに、テキストファイルから読み取った名前を入力しました。ボタンをクリックして、名前とその他の情報を入力したい既知のウィンドウを開きます。同じファイルから。
これが私のコードです:これは私のメインフレームです

これは私の2番目のcclassです:

public class ShowDetails extends JFrame{

public ShowDetails(){
this.gui = gui;
fereastra();
}
public void fereastra(){
JPanel panel = new JPanel(new GridLayout(2, 2));
JTextArea text = new JTextArea();
text.setEditable(true);
text.setText(gui.readFile("Persoane.txt"));
text.getText();
panel.add(text);
getContentPane().add(panel);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//setLocation(50,50);
setSize(300,200);
setResizable(false);
// setVisible(true);
show();
}
