Question

我的问题是让我的Main类和Journal类连接在一起，在Main类中用户将输入两个变量并单击按钮来创建表，在Journal类中，它将采用这两个变量并使其通过一个进程在它们被添加到表之前所以我需要JTextField1作为变量a和JTextField2作为变量b。

我使用netbeans来创建Main类和我自己创建表类的方法请帮忙！谢谢！这是主要类Netbeans告诉我在右键单击＆gt;时编辑的部分。活动＆gt;行动＆gt;行动执行

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
     int data1 = Integer.parseInt(jTextField1.getText());
     int data2 = Integer.parseInt(jTextField2.getText());

}

这是我的代码：

package Components;

    public JTable getTable() {
        return table;
    }

    private static void gui()
    {
        JFrame gui = new JFrame();
        gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        gui.setTitle("Journal List");
        gui.setSize(700,200);
        gui.setLocationRelativeTo(null);
        gui.setVisible(true);
        gui.add(new Journal());
    }


}

请帮助添加任何内容或删除我的代码中的任何内容以使其正常工作，谢谢:)

在你的缩窄器上写下

public static void main(String args[]){
Journal is= new Journal();


}
public Journal() 
{...}

使用JButton将JFrame连接到JPanel，JTextFields出现问题
