使用的JButton連接的JFrame到JPanel的JTextField的

Question

我的問題是讓我的主類和雜誌類連接在一起，在Main類用戶的問題將輸入兩個變量，點擊按鈕來創建表，在雜誌類，它將採取這兩個變量，並讓它通過一個進程之前，他們被添加到表中，所以我需要JTextField1作爲變量a和JTextField2作爲變量b。

我使用NetBeans中創建主類和我自己的方法來創建表類，請幫助！謝謝！這是主類的部分Netbeans的告訴我編輯，當我點擊右鍵>活動>動作>執行的操作

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

}    

這裏是我的代碼：

package Components;

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


} 

請幫助添加任何東西或刪除任何東西在我的代碼，以使他們的工作，謝謝:)

寫的是在你的大蟒

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


} 
public Journal() 
{...}
