Java绘图：绘制虚线与实线 　　public LineDemo(){ 　　 super("实线与虚线"); //调用父类构造函数 　　 setSize(300,200); //设置窗口尺寸 　　 setVisible(true); //设置窗口可视 　　 setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //关闭窗口时退出程序 　　} 　　public void paint(Graphics g){ //绘制组件方法 　　 Graphics2D g2=(Graphics2D)g; //得到2D图形 　　 Dimension dim = this.getSize(); //得到组件尺寸 　　 g2.setColor(Color.white); //设置绘制颜色为白色 　　 g2.fillRect(0, 0, dim.width, dim.height); //填充整个组件 　　 g2.setColor(Color.black); //设置绘制颜色 　　 g2.drawLine(40,160,280,160); //绘制实线 　　 g2.drawLine(40,160,40,40); 　　 g2.drawString("0",30,165); //绘制字符串 　　 g2.drawString("100",16,50); 　　 g2.drawString("200",270,175); 　　 float[] dash={5,5}; //短划线图案 　　 BasicStroke bs = new BasicStroke(1,BasicStroke.CAP_BUTT,BasicStroke.JOIN_MITER, 10.0f,dash,0.0f); //实例化新画刷 　　 g2.setStroke(bs); //设置新的画刷 　　 g2.drawLine(40,160,100,120); //用新的画刷绘制虚线

这是用VB写的PCB钻孔机的钻孔数据处理程序，可以对钻孔精度进行分析。(It is written in VB PCB drilling machine drilling data processing program, you can drill precision analysis.)

说明：  它默认提供了图片碎片组合特效，百叶窗特效，波浪特效，拼图动画特效等效果。另外它还提供了很多参数来设置各种不同的拼图动画效果(By default, it provides image fragmentation combination effects, louver effects, wave effects, puzzle animation effects and so on. In addition, it also provides many parameters to set various puzzle animation effects.)

For any software that handles client requests, at some point, there must be a persistent point where all data related to the clients are stored. Those storages can be any thing (database, mainframes, files etc.). What if this software needs to access those storages with concurrent requests, knowing that opening a connection is memory and CPU consuming? A Connection Pool is a container of open and reusable connections. It will help you save both memory and CPU time. Also, it will help you in managing connections.
