textfieldkey.java

java2参考大全上的例子的源码和自己的理解.

import java.awt.*;

public class textfieldkey
    extends
    java.applet.Applet {
     public void init()
 {   GridBagLayout layout=new GridBagLayout();
      setLayout(layout);
      GridBagConstraints GBC = new
                                                 GridBagConstraints();
         Button button1=new Button("button1");
         Button button2=new Button("button2");
         Button button3=new Button("button3");
         Button button4=new Button("button4");
         Button button5=new Button("button5");
         Button button6=new Button("button6");
         Button button7=new Button("button7");
         Button button8=new Button("button8");
         Button button9=new Button("button9");
 }
 }
