JAVA如何给程序设置一个窗口
首先，绘制一个默认的窗体，创建好工程，包，类，命名类为Window.很简单，在类中添加一个私有属性JFrame，这么写：private JFrame f = new JFrame("欢迎来到本自助银行");Window的构造方法中，只写 f.setVisible(true);以及窗体的初始位置和初始大小：f.setLocation(300, 200);f.setSize(800, 500);
然后在同一个构造函数中跟进一行f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);此为设置关闭图标即退出程序紧接着，写f.setResizable(false);此为设置不可更改窗体大小。如图，的确没办法更改了。
最后，便是画龙点睛的一笔，给窗体添加一个图标，显得更专业了一些：f.setIconImage(Toolkit.getDefaultToolkit().createImage("E:\\a.jpg"));
这里有一点比较重要，重申一句。构造器中的设置比静态属性初始化设置更有直接影响力。而且，程序是执行向上覆盖的。也就是说，如果之后有过更改，那么更改之后就显示更改后的结果，比如，在这个构造函数中再写f.setTitle("好好活着");那么，请注意窗体的文字。如图：

如何在windows命令行窗口运行Java程序
1、首先，运行Java程序，需要安装好jdk
2、在windows命令行窗口输入java和javac验证环境变量path是否配置好
3、编写好正确的java小程序
4、在windows命令行进入到程序所在路径下，javac编译，会在原有程序下新生成一个.class文件，java运行.class文件，就可以成功运行Java程序啦
java窗口程序制作
不知道你要连什么数据库的说.
硬性规定要用数据库的么,要是要的话,你可以自己改改下面的代码的说.

char[] passwordStrAry = passwordField.getPassword();

if (username == null || password == null || "".equals(username)

JOptionPane.showMessageDialog(null, "密码和用户名不能为空", "注意",
JOptionPane.ERROR_MESSAGE);
if (username == null || "".equals(username))
userNameField.grabFocus();
else
passwordField.grabFocus();
return;
}
boolean checkResult = UserManager
.loginCheck(username, password);
if (!checkResult) {
JOptionPane.showMessageDialog(null, "密码或用户名不正确", "注意",
JOptionPane.ERROR_MESSAGE);
} else {
new MessageFrame("登录成功，欢迎光临！", getLocation());
dispose();
}
}
});
register.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
new RegisterFrame("注册界面", getLocation());
dispose();
}
});
setLayout(new FlowLayout());
add(panel);
setSize(250, 130);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}这个是登录界面的代码的说
