我有一个运行GUI的applet。我想从我的其他程序中调用此GUI。我知道我需要将这个applet变成一个应用程序。我有一个init（）和一个actionPerformed（ActionEvent ae）。我该怎么办？
我的代码：
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;

答案 0 :(得分：3)
说实话，您需要从头开始重新编写程序，以便可以合并OOP技术，数组，集合以及Java提供的其他优势。我建议：
答案 1 :(得分：2)
只需添加一个main（）方法，为applet创建一个Frame，将applet添加到框架中，然后调用applet的init（）和start（）方法。请参阅我的Mandelbrot.java以获取示例：http://unixshell.jcomeau.com/src/java/com/jcomeau/Mandelbrot.java
这种方法的一个优点是它可以与任何现有的applet一起使用，以允许它作为applet或应用程序运行。如果您正在使用Swing组件，请使用JFrame，否则它应该几乎相同。
答案 2 :(得分：0)
通常，您需要将所有非摆动组件更改为摆动组件。对于事件，它们对于applet和swing应用程序大致相同。希望它有所帮助。
答案 3 :(得分：0)
我不确定你在问什么，但是如果你想在窗户里面，你需要做的就是：
public Object[] startNewSurvey()
{
java.awt.Frame f = new java.awt.Frame("You're title here.");
f.setSize(new Dimension(<Width>, <Height>));
f.setResizable(false);
survey s = new survey();
s.init();
f.add(s);
f.setVisible(true);
return new Object[] { f, s };
}
这将只是一个全新的框架实例，并在该框架中放置您的调查类的另一个新实例，然后显示它。它还返回一个2大小的Object []数组，其中包含新的Frame和调查实例。希望有所帮助。
