Frame和JFrame代碼比較:

**包

      Frame----import java.awt.*;

      JFrame----import javax.swing.*;

**JFrame多了一個對于窗體字段的定義但是沒有TextArea

**JFrame要先對窗體字段進行賦值

                 設置右上旋鈕的作用

**初始化方法的時候：

      按鈕動作事件的處理：

/*but.addActionListener(new ActionListener(){

                 publicvoid actionPerformed(ActionEvent e){

                      JDialogdialog =new JDialog(thisFrame,"JDialog的對話框：");

                       dialog.setModalityType(JDialog.ModalityType.application_MODAL);

                      dialog.setLocation(thisFrame.getX() +50,thisFrame.getY()+90);

                      dialog.setSize(200,150);

                      dialog.add(new JLabel(tex.getText()+",zoa"));

                      dialog.setVisible(true);

                 }

           });

*/

/*

but.addActionListener(new ActionListener(){

                 publicvoid actionPerformed(ActionEvent e){

                      ta.setText(tf.getText() +"愛你！");

                 }

           });

           this.addWindowListener(new WindowAdapter(){

                 publicvoid windowClosing(WindowEvent e){

                      System.exit(0);

                 }

           });
