1. 1

   新建一個java項目。

   0結構辦理器

   
2. 2

   新建一個類，取名jframe2。

   
3. 3

   打開jframe2.java這個文件，把代碼點竄為：

   public class jframe2 extends javax.swing.JFrame{

       public jframe2(){

           buju();

       }

       private void buju(){

      

       }

       public static void main(String[] arg){

       }

   }

   
4. 4

   界說用到的變量。

   
5. 5

   在buju這個方式中初始化變量：new 類。

   
6. 6

   關頭代碼：

   this.getContentPane().setLayout(new java.awt.GridBagLayout());

   窗口結構設為GridBagLayout

   gridBagConstraints.gridx = 0;結構0列

   gridBagConstraints.gridy = 0;結構0行

   gridBagConstraints.gridwidth=1;     幾多列

   gridBagConstraints.gridheight=1;    幾多行

   gridBagConstraints.weightx=1;   分派程度空間

   gridBagConstraints.weighty=1;    分派垂直空間

   gridBagConstraints.fill=java.awt.GridBagConstraints.HORIZONTAL填充，程度，垂直，

   gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 5);外側空間

   
7. 7

   buju方式中完整代碼：

    java.awt.GridBagConstraints gridBagConstraints;

           setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

   添加main方式中代碼：

   java.awt.EventQueue.invokeLater(new Runnable(){

               @Override

               public void run(){

                   new jframe2().setVisible(true);

               }

           });
