转换现有的applet介绍可执行jar文件
[英]convert existing applet intro executable jar file
问题描述
I'm learing java at school so I made some tasks but i want to be able to make an executable file out of it so i can send it to some friends to show what i made. 
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。 I found on this site that you have to use JFrames and some things like that but i don't know how that works. 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。 Did some research about that but i can't find an easy way to convert it without redoing almost all of my code. 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。 My code is below, could somebody please help me? 我的代码如下，有人可以帮帮我吗？

- Make your class extend
JFrameinstead ofJApplet.使您的类扩展JFrame而不是JApplet。 Have a constructor and call
init()from there有一个构造函数并从那里调用init()public Kueze(){ init(); }Have a
mainmethod that you instantiateKuezeint有一个实例化Kuezeint的main方法public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable(){ @Override public void run() { new Keuze(); } }); }In your
init()you'll also want to do the normalJFrameroutine also在你的init()你也想要做普通的JFrame例程public void init(){ .... setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); pack(); setLocationRelativeTo(null); setVisible(true); }See the JFrame docs to see what those methods do
请参阅JFrame文档以了解这些方法的作用
SIDE NOTES 侧面说明
- You have alot of AWT going on in your program. 你的程序中有很多AWT正在进行中。 You should really look into Creating a GUI with Swing 您应该真正研究使用Swing创建GUI
- Don't
setSize(...).不要setSize(...)。 I already shows you how topack()我已经告诉你如何pack() - Why in the world is there so much going on in your
paintmethod?为什么世界上你的paint方法有这么多 ？ The only thing you want in the paint method, are things that are actually doing the painting.你在paint方法中唯一想要的就是实际进行绘画的东西。 - call
super.paint(g);叫super.paint(g);right below the methodpublic void paint在方法public void paint
UPDATE UPDATE
Your code is too long to post on here, so I'll give you the layout 你的代码太长了，无法发布在这里，所以我会给你布局

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
@Override

If you want to be able to use the code as both an applet and an application you can wrap everything in a JPanel and then set that JPanel as the content pane for both the applet and the application. 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.*;
import javax.swing.JApplet;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Keuze extends JApplet {
public static void main(String[] args) {
JFrame window = new JFrame("Application Name");
MyPanel content = new MyPanel();
window.setContentPane(content);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.pack();
window.setVisible(true);
}
public void init() {
MyPanel content = new MyPanel();
setContentPane(content);
}
}
class MyPanel extends JPanel {
Choice kleur, vorm;
Label titel, lblKleur, lblVorm, parameters, lblParameter1, lblParameter2, lblParameter3, lblParameter4, lblParameter5, lblParameter6;
TextField parameter1, parameter2, parameter3, parameter4, parameter5, parameter6, tekst;
Button teken, vergrendel1, vergrendel2;
Integer intParameter1, intParameter2, intParameter3, intParameter4, intParameter5, intParameter6, x, y, lengte, grootsteX, grootsteY, kleinsteX, kleinsteY, intParameter7, intParameter8, intParameter9, intParameter10, intParameter11, intParameter12, intVorm, intKleur, intParameter13, intParameter14, intParameter15, intParameter16, intParameter17, intParameter18, intKleur2, intVorm2;
Boolean draw, draw2, draw3;
Polygon driehoek, driehoek2, driehoek3;
String strTekst, strTekst2, strTekst3;
MyPanel() {
draw = false;
draw2 = false;
draw3 = false;
/* The rest of your original init() */
}
public void paint(Graphics g) {
super.paint(g);
setSize(750, 750);
intParameter1 = Integer.parseInt(parameter1.getText());
intParameter2 = Integer.parseInt(parameter2.getText());
intParameter3 = Integer.parseInt(parameter3.getText());
intParameter4 = Integer.parseInt(parameter4.getText());
intParameter5 = Integer.parseInt(parameter5.getText());
intParameter6 = Integer.parseInt(parameter6.getText());
/* The rest of your original paint(Graphics g) */
}
public boolean action(Event e, Object o) {
/* The rest of your action method */
}
}
