在没有Gui编辑器的情况下向Gui添加3个jTextArea

Question

我已经完成了一名学生的工作，我的任务是为它编写一个自动文本编辑接近完成的任务。我必须将3或4个jTextAreas添加到gui中。问题在于他如何编写代码，我只能添加一个jTextArea。

这是怎么样了，它看起来像1 Jtextarea：

而且这是我希望它有它：

这里是疥癣的代码键盘布孔布局：

  button = new CustomJButton[button_size]; 
      jPanel1 = new javax.swing.JPanel(); 
      jPanel2 = new javax.swing.JPanel(); 
      jTextArea = new javax.swing.JTextArea(); 

      // BorderLayout 
      bl = new java.awt.BorderLayout(); 
      this.setLayout(bl); 
      this.add(jTextArea, BorderLayout.NORTH); 
      Font font1 = new Font("SansSerif", Font.BOLD, 20); 
      jTextArea.setFont(font1); 
      jTextArea.setFocusable(false); 



      menuButtongbc = new GridBagConstraints(); 
      // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL/VERTICAL 
      menuButtongbc.fill = GridBagConstraints.BOTH; 
      menuButtongbc.insets = new Insets(1,1,1,1); 
      menuButtongbc.weightx = 1; 
      menuButtongbc.weighty = 1; 

      letterButtongbc = new GridBagConstraints(); 
      // vergrößert die Buttons in BEIDE Richtungen // HORIZONTAL/VERTICAL 
      letterButtongbc.fill = GridBagConstraints.BOTH; 
      letterButtongbc.insets = new Insets(1,1,1,1); 
      letterButtongbc.weightx = 1; 
      letterButtongbc.weighty = 1; 

      jPanel1.setLayout(new java.awt.GridBagLayout()); // Layout left side 
      jPanel2.setLayout(new java.awt.GridBagLayout()); // Layout right side

      for (int menuButtonArray = 0 ; menuButtonArray < 4 ; menuButtonArray++){ 
       CustomJButton a = new CustomJButton(); // a : Hilfsvariable 
       button[menuButtonArray] = a; 
       button[menuButtonArray].setFont(new Font("Arial", Font.PLAIN, 40)); 
       button[menuButtonArray].setBackground(backgroundColor); 
       button[menuButtonArray].setOpaque(true); // Test für MAC 
       button[menuButtonArray].setMinimumSize(new java.awt.Dimension(75, 75));

       button[menuButtonArray].setFocusable(false); 
       button[menuButtonArray].setBorder(BorderFactory.createLineBorder(Color.black, 4)); 

       menuButtongbc.gridx = xVar; // X und Y Zuweisung der Button im GridbagLayout 
       menuButtongbc.gridy = yVar; // X und Y Zuweisung der Button im GridbagLayout 
       xVar++; 
       if(xVar == 2){ yVar++ ; xVar = 0; } 

       jPanel1.add(button[menuButtonArray] , menuButtongbc); 
      }

创建一个水平框并在水平框中输入3个文本框。

Box hBox= Box.createHorizontalBox(); 
hBox.add(TextArea1); 
hBox.add(TextArea2); 
hBox.add(TextArea3);
