使用JButton将JTextField输出到一个新窗口



我有个问题。如果您按下"提交"按钮，在这些JTextField、单选按钮和复选框上输入的所有值是否可以打印/显示在新窗口上？请帮我了解更多。

我在这里用Spring Layout做了一个简单的报名表，因为我认为它很适合

这是我的代码：

  import java.awt.Component;
   import java.awt.Container;
   import java.awt.Font;
   import java.awt.BorderLayout;
   //import java.awt.GridLayout;
   import javax.swing.JFrame;
   import javax.swing.JLabel;
   import javax.swing.JTextField;
   import javax.swing.SpringLayout;
   import javax.swing.JRadioButton;
   import javax.swing.ButtonGroup;
   import javax.swing.JButton;
   import javax.swing.JComboBox;
   import javax.swing.JCheckBox;
   import javax.swing.JPanel;
   import java.awt.event.ItemEvent;
   import java.awt.event.ItemListener;

   class SpringSample {
   public static void main(String args[]) {
   JComboBox bDay;
   JComboBox days;
   JComboBox taon;
   JButton butones;
   JFrame frame = new JFrame("Enrollment Form");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   Container contentPane = frame.getContentPane();
   //JLabel title = new JLabel("Enrollment Registration");
   SpringLayout layout = new SpringLayout();
   contentPane.setLayout(layout);
   JPanel mainPanel = new JPanel(new BorderLayout());
   /*JLabel titles = new JLabel("Enrollan na!");
   Font font = new Font("Agency FB", Font.BOLD, 50);
   titles.setFont(font);
   mainPanel.add(titles, BorderLayout.PAGE_START); */

   //last name
   Component last = new JLabel("Last Name:");
   Component last2 = new JTextField(15);
   contentPane.add(last);
   contentPane.add(last2);
   layout.putConstraint(SpringLayout.WEST, last, 10, SpringLayout.WEST,   
   contentPane);//pweto nugn name
   layout.putConstraint(SpringLayout.NORTH, last2, 25, SpringLayout.NORTH, 
   contentPane);//gaano kataas o kababa yung box
   layout.putConstraint(SpringLayout.NORTH, last, 25, SpringLayout.NORTH,

frame.setSize(500, 550);    
frame.setVisible(true);
}
}

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JTextFiled中的内容，您可以尝试JOptionPane.ShowMessageDialog（null，"text here"）；

这将弹出一个消息框，其中包含你输入的w.e文本。。。所以你想要的文本是：

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

为了在单击提交按钮时实现这一点，您需要在该按钮中添加一个ActionListener，因此它将类似于：

 submitButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent evt){
  JOptionPane.ShowMessageDialog(null,"text here");
  }
 });

首先从的所有字段中获取所有信息

语法：字符串s=xx.getText（）.toString（）；

检索信息后，单击按钮使用

Joptionpane.showMessageDialogue（null，s）；

它在对话框中显示文本字段信息
