Applet or application wont compile now?
I recently got a new computer at work. After I set everything up, including jre & sdk 1.4.1, and path file ifno on my windows xp box (same setup as the other machine), my same applications are now throwing errors?
It's as if for some reason my old setup was more lax on catching compile time errors.
Whats even weirder, is the old applets and applications compiled on my old machine still run fine and if I try to compile the old applets and applications without resaving them, I get no error, its just after I resave them, even if I only add a blank line to the file.
any suggestions
Jason
any suggestionsYes, tell us what the errors are exactly! And you should probably show relevant parts of the code too.

When i updated my computer, my safari on applications wont open and says "safari quit unexpectedly" and wont open but when i open it on the application key on the mac, safari will open. how do i get safari back on my dock where it will open. when i click reopen it wont. but i know safari works because thats what im using right now. it just wont open when i click the one i had loaded on my dock and in applications. please help!
StephanieDrag the Safari icon straight up and off the Dock so it goes, "poof" ...
Now click and hold the Safari app in the Applications folder and drag that to the Dock.
See if you can open a webpage in Safari. -

please help me! i beg for ur help!!!!!!!!application->applet
get rid of static variables. if nothing else helps put all your static variables in a class that does nothing but holding them and initialize only one such class and add a reference to it in every of your classes.
whatever you have done in the main method do it now in the constructor of that class.
from your applet (or if you have none make one that does nothing else) construct an instance of that class
applet->application
put all you have drawn directly on the applet ontpo some sort of window.
change the init method to a constructor.
make a class with a main method that constructs such an exapplet -

Arrays - confusing, wont compile, please help! ?:-)
Hello everyone,
I am new to the java forum, and I think its a fantastic idea. I am extremely stuck with my java, I have been workin on the same piece of code for at least 20 hours in total, 8 of which I spent in the last day, and to much of my frustration, the buggery code just wont compile. Im assuming many of you are probably laughing at me by now, lol, its ok, After my inital stress and hair pulling, all I could do was laugh. But I refuse to give up on the code after spending so long, and I have a feeling Im so close, its based around arrays, anyway I'll stop blabbering and post the code I have wrote, and if any of you could solve why it wont compile, it would be greatly appreciated.
Heres my code:
import avi.*;
public class CDCollection
private String title = "Unknown";
private String artist = "Unknown";
private int quan = 0;
private double price = 0;
CDCollection(double cdPrice, int cdQuan, String cdTitle, String cdArtist)
title = cdTitle;
artist = cdArtist;
quan = cdQuan;
price = cdPrice;
return price;
public static int findHighest(CDCollection[] cd) {
int highestSoFar = -1; // lower than any valid
for (int i = 0; i < cd.length; i++) {
if (cd.CDCollection() > highestSoFar) {
highestSoFar = cd[i].CDCollection();
return highestSoFar;
// instance method to write out cd details
public void cdDetails(Window screen)
screen.write("�"+price+"\t"+quan+"\t"+title+"\t"+artist+"\n");
class CDMain
public static void main(String[] args)
Window screen = new Window ("CDMain", "bold", "black", 14);
screen.showWindow();
screen.write("CD List:\n\n");
CDCollection cd1 = new CDCollection (10.99,11,"All Killer No Filler","Sum 41");
cd1.cdDetails(screen);
CDCollection cd2 = new CDCollection (12.99,8,"The best of","Sting");
cd2.cdDetails(screen);
Essentially wot Im tryin to do, is create a cd collection program, whereby details of the cd are entered (price, quantity, title and artist) and I would like to return statistical data on the cd collection, such as total number of cds, most expensive and cheapest cds etc. As you can I see I have tried to use arrays to find out the most expensive cd, but it still wont work! Please help, anyone, as Ive exhausted myself on this piece of code, Ive been through books, and I still cant bloody do it. :( lol
Thanks in advance,
All the best,
Larry :-)Hi!
First you never call your method findHighest.
Second you do not have an array of your CD's. You only have two instances of it.
Try this:
CDCollection[] cds = new CDCollection[2];
CDCollection cd[0] = new CDCollection (10.99,11,"All Killer No Filler","Sum 41");
cds[0].cdDetails(screen);
CDCollection cds[1] = new CDCollection (12.99,8,"The best of","Sting");
cds[1].cdDetails(screen);
int highest = CDCollection.findHighest(cds);
And:
public static int findHighest(CDCollection[] cd) {
double highestSoFar = -1; // lower than any valid
for (int i = 0; i < cd.length; i++) {
if (cd.getPrice() > highestSoFar) {
highestSoFar = cd[i].getPrice();
return highestSoFar;
And in your CDCollection class you need a method:
public double getPrice()
return this.price;
I hope I did no mistake in here but it should work!

Hi dip_kinu,
I apologize, I'm a bit unclear on exactly what device you are trying to set up and what is happening when you try to do so. If you are having issues remembering your Apple ID, or feel like you may have set up multiple Apple ID's, you may find the following page helpful:

To convert applet-based application?
Hi
There are some tools on market to run an applet-based application on server side. Those tools convert the behavior of applet application to Jsp application. So they run the application on web server and send HTML to web browser.
One of those tools is WebCream(www.creamtec.com)
Would appreciate to let me know other tools or any other ways to achive this.
Thanks in Advance.repost

I have a apple ipod touch but recently I restored all the settings, as well as the applications. But now I am not able to add songs to it. There is blank screen that shows the symbol like to connect to itunes first. I'm not able to use that... Please help
The iPod's firmware is corrupt. You'll need to restore it again in iTunes. If necessary, place the iPod in recovery mode for iTunes to recognize the device. Use the instructions in this Apple support document to walk you through the process of placing the iPod Touch into recovery mode.
iOS: Unable to update or restore

A movie i rented on itunes wont download now what do i do?
a movie i rented from itunes wont download now what do i do?
Hey Patiencepieart!
While there is not enough information in the post about your circumstance to be able to say for sure, but here are some tips from the iTunes movie rental FAQ that may be helpful to you:
iTunes Store: Movie rental frequently asked questions (FAQ)
http://support.apple.com/kb/ht1657
Where can I watch my movie rental?
You can watch your movie rental on your computer, iPhone, iPad, iPod touch (with iOS 3.1.3 or later), iPod classic, iPod nano (3rd, 4th, or 5th generation), or on your TV using your Apple TV. You can watch HD movie rentals on your computer, iPhone 4 or later, iPad, iPod touch (4th generation or later), or with Apple TV.
How many times can I view the movie?
Once you start watching your movie, you can view the rented movie as many times as you wish within the 24-hour (or 48-hour) window.
What happens to my rented movie if I don't watch it?
If you don't watch your rented movie, it will expire in 30 days and disappear from your iTunes library. You will need to rent it again in order to watch it.
Can I play my rental on more than one device?
If you download a rented movie on your computer: You can transfer it to a device such as your Apple TV (1st generation), iPhone, iPad, or iPod if it’s a standard-definition film (movies in HD can only be watched on your computer, iPad, iPhone 4 or later, iPod touch (4th generation or later), or Apple TV). Once you move the movie from your computer to a device, the movie will disappear from your computer's iTunes library. You can move the movie between devices as many times as you wish during the rental period, but the movie can only exist on one device at a time.
If you download a rented movie on your iPhone 4 or later, iPad, iPod touch (4th generation or later), or Apple TV: It is not transferable to any other device or computer.
Take care, and thanks for visiting the Apple Support Communities.
Cheers,

Hi To All,
I'm converting a Applet into Application.
All the things are runing well but when my Applet gets to try the access getDocumentBase() method
its giving a nullPointerException
My all code is written below please help me to find out the problem
import java.awt.Frame;
import java.awt.event.*;
import java.awt.Dimension;
import java.applet.Applet;
// Applet to Application Frame window
public class AppletFrame extends Frame implements java.awt.event.WindowListener
public static void startApplet(String className, String title,String args[])
{ Dimension appletSize;
try
// create an instance of your applet class
myApplet = (Applet) Class.forName(className).newInstance();
catch (ClassNotFoundException e)
{ System.out.println("AppletFrame " + e);
return;
catch (InstantiationException e)
System.out.println("AppletFrame " + e);
return;
} catch (IllegalAccessException e)
System.out.println("AppletFrame " + e);
return;
} // initialize the applet myApplet.init();
myApplet.start();
AppletFrame f = new AppletFrame(title);
f.add("Center", myApplet);
f.addWindowListener(f);
appletSize = myApplet.getSize();
f.pack();
f.setSize(appletSize);
f.show();
public AppletFrame(String name)
{ super(name);
} public void windowClosing(java.awt.event.WindowEvent ev)
{ myApplet.stop();
myApplet.destroy();
java.lang.System.exit(0);
} public void windowClosed(java.awt.event.WindowEvent ev) {}
public void windowActivated(java.awt.event.WindowEvent ev) {}
public void windowDeactivated(java.awt.event.WindowEvent ev) {}
public void windowOpened(java.awt.event.WindowEvent ev) {}
public void windowIconified(java.awt.event.WindowEvent ev) {}
public void windowDeiconified(java.awt.event.WindowEvent ev) {}
private static Applet myApplet;
public static void main(String args[]){
startApplet("appletImageBook.appletImage.Standalone2","XApplets",args);
====================================================
And Standalone2.java is
public class Standalone2 extends Applet {
Image img ;
public void init()
{ add(new Button("Standalone Applet Button"));
img = getImage(getDocumentBase(),"images/office1.jpg");
public void paint(Graphics g) {
g.drawImage(img,0,0,null);
=====================================================
And while runing AppletFrame.java it is giving Error below
===============================
Exception in thread "main" java.lang.NullPointerException at java.applet.Applet.getDocumentBase(Applet.java:125)
at appletImageBook.appletImage.Standalone2.init(Standalone2.java:20) at appletImageBook.appletImage.AppletFrame.startApplet(AppletFrame.java: 38)
at appletImageBook.appletImage.AppletFrame.main(AppletFrame.java:99)
===============================
Any type of help will be fine for me
Thanks in advanceThe only difference between an applet and an application should be the way they are started.
Instead of adding an applet to a frame, open a frame from the applet. Open the same frame from your application.
Or instead of a frame, use a (J)Panel. Add it directly to your applet, or add it to a new frame when you want to run it as an application.
In any case: separate the way the UI is created from the way the application is started.
