flowlayoutdemo.java

java经典的源代码 我非常喜欢这个源代码 对于编程很有好处

import java.awt.*;
import java.awt.event.*;
public class FlowLayoutDemo extends Frame
{
  private Button left,right,center;
  private FlowLayout layout=new FlowLayout();
        public FlowLayoutDemo()
        {
          super("FlowLayout Demo");
          this.setLayout(layout);
          left=new Button("Left");
          this.add( left);
          center=new Button("Center");
          this.add(center);
          right=new Button("Right");
          this.add(right);
        }
        public static void main( String[] args )
        {
                FlowLayoutDemo f=new FlowLayoutDemo();
                //设置框架窗体的事件监听(关闭窗体事件)
                f.addWindowListener(new WindowAdapter(){
                        public void windowClosing(WindowEvent e)
                        {
                                System.exit(0);
                        }
                }); 
                f.pack();
                f.show();
        }
}
