Java 使用JButton将JTextField输出到新窗口

我有个问题。如果按“提交”按钮，是否可以在新窗口上打印/显示在这些

JTextField

s、单选按钮和复选框上输入的所有值？请帮助我了解更多

我在这里使用Spring布局制作了一个简单的报名表，因为我认为它非常适合

这是我的密码：

此代码仅显示接口程序。一个简单的界面。

如果您只想在新窗口上显示jtextfield中的内容，您可以尝试 ShowMessageDialog（null，“此处文本”）

这将弹出一个消息框，其中包含w.e文本u put。。。因此，您想要的文本是：

address1.getText()+"\n"+.... 

为了在单击submit按钮时实现这一点，您需要向该按钮添加ActionListener，因此它类似于：

 submitButton.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent evt){

  JOptionPane.ShowMessageDialog(null,"text here");
  }
 });

---

首先从所有字段获取所有信息

语法： 字符串s=xx.getText（）.toString（）

检索完按钮上的信息后，单击 使用

showMessageDialogue（null，s）

---

它在对话框中显示文本字段信息

如？您好。六羟甲基三聚氰胺六甲醚。。。是的，它类似于我想要发生的输出。但区别在于它不会显示在新窗口上。不过还是谢谢你。请格式化你的代码。目前很难阅读。@Naomi:

JOptionPane

提供了几种静态工厂方法来创建

JDialog

的实例，每个实例都是一个

窗口；用于创建一个较短的、完整的、关注问题的文档。另见此。
