Converting application to applet
I ended up making a temperature conversion tool for my school assignment, but after making it an application, it ended up needing to be an applet. I was able to find this post that someone else started: http://forum.java.sun.com/thread.jspa?threadID=390846&messageID=1689271 but the format of my application looks to be a little more complex. Do I just need to replace
publicstaticvoid main(String[] args){
javax.swing.SwingUtilities.invokeLater(new Runnable(){
publicvoid run(){
createAndShowGUI();
}
});
}
with
/** Initializes AppletOne */
publicvoid init(){
createAndShowGUI();
}
but I'm not sure what to do with javax.swing.SwingUtilities.invokeLater(new Runnable()
Just for reference, here is my whole code as an application:/**
