I have an applet that runs a GUI. I want to call this GUI from my other program. I know that I need to turn this applet into an application. I have an init() and a actionPerformed(ActionEvent ae). How can I do it?
My code:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
public class survey extends Applet implements ActionListener
{
private TextField question;
private Button enter, start;
int count = 0;

int b = 0;
int c = 0;
int d = 0;

Just add a main() method, make a Frame for your applet, add the applet to the frame, and call the applet's init() and start() methods. See my Mandelbrot.java for an example: https://jcomeau.com/src/java/com/jcomeau/Mandelbrot.java
One advantage of this approach is that it can be used with any existing applet, to allow it to function as either an applet or application. Use a JFrame if you're using Swing components, otherwise it should work pretty nearly the same.

Following are the changes to be made from Applet to Application

I'm not sure what you are asking, but if you want it inside a window all you need to do is this:
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 };
}
That will just instance a brand new frame and put another new instance of your survey class in that frame, then display it. It also returns a 2 sized Object[] array containing the new Frame and survey instances made. Hope that helps.

In all honesty, you need to re-write your program from scratch so that you can incorporate OOP techniques, arrays, collections, and other advantages that Java has to offer. I recommend:

In general, you'll want to change all the non swing components to swing components. For events, they're roughly the same for both applets and swing applications. Hope it helps.
