我有我的原始文本字段在我的第一幀，我需要它顯示在我的其他jframe。該代碼是：從一個Jframe傳遞信息到另一個
JButton btnContinue = new JButton("Continue");
btnContinue.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String msg = nameL.getText();
frame2 fram = new frame2();
fram.setVisible(true);
frame.dispose();
new order (msg) .setVisible(true);
「NAMEL」是用戶在輸入自己的名字文本框中
此代碼描述它應顯示：
public order(String para){
getComponents();
JLabel lblNewLabel_1 = new JLabel("");
lblNewLabel_1.setBounds(91, 27, 254, 84);
contentPane.add(lblNewLabel_1);
lblNewLabel_1.setText(para);
這是我的第一課堂，用戶輸入他們的名字

getComponents();

你的問題確切的是什麼？ – Berger
用戶在文本字段中輸入他們的名字，它將它們帶到一個訂單屏幕，當他們去「收據」jframe時，他們應該有他們的名字出現，我無法找到一種方法來轉移它，嘗試了很多方法，沒有什麼作品。 @Berger –
看來你的代碼已經在做這件事了，什麼都行不通？也許增加整個類，以便我們可以更好地看到問題。 – Berger
