我在学校学习java所以我做了一些任务，但我想能够制作一个可执行文件，所以我可以把它发送给一些朋友来展示我做的。我在这个网站上发现你必须使用JFrames和类似的东西，但我不知道它是如何工作的。做了一些研究，但我找不到一个简单的方法来转换它，而无需重做几乎所有的代码。我的代码如下，有人可以帮助我吗？

JFrame而不是JApplet。 有一个构造函数并从那里调用init()
public Kueze(){
init();
}
使用main方法实例化Kueze int
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
@Override
public void run() {
new Keuze();
}
});
}
在您的init()中，您还需要执行正常的JFrame例程
public void init(){
....
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setLocationRelativeTo(null);
setVisible(true);
}
请参阅JFrame docs了解这些方法的用途
侧面说明
setSize(...)。我已经向您展示了如何pack() paint方法中有这么多？在paint方法中你唯一想要的就是实际进行绘画的东西。super.paint(g); public void paint

如果您希望能够将代码同时用作applet和应用程序，则可以将所有内容包装在JPanel中，然后将该JPanel设置为applet和应用程序的内容窗格。
import java.awt.*;
