mailSendFrame.java源程序代码如下：

public class mailSendFrame extends Frame {
smtpMail mailSender=new smtpMail();
Panel panelMain = new Panel();

Panel panel10 = new Panel();
Button cmdSend = new Button();
Button cmdExit = new Button();
private FileDialog openFileDialog
= new FileDialog(this,"打开文件",FileDialog.LOAD);
public mailSendFrame() {
try {
Init();
}
catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
mailSendFrame mailSendFrame = new mailSendFrame();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = mailSendFrame.getSize();
if (frameSize.height ＞ screenSize.height) {
frameSize.height = screenSize.height;
}
if (frameSize.width ＞ screenSize.width) {
frameSize.width = screenSize.width;
}
mailSendFrame.setLocation((screenSize.width - frameSize.width) / 2,
(screenSize.height - frameSize.height) / 2);
mailSendFrame.setVisible(true);
mailSendFrame.show();
}
private void Init() throws Exception {
this.setLayout(new BorderLayout());
panelMain.setLayout(new GridLayout(2,1));
panelUp.setLayout(new GridLayout(6,1));
panel3.setLayout(new FlowLayout());
this.setVisible(true);
