Try it again. And this time write down the error message you get so you can ask a coherent question.

Can't see why I can't compile this

I can't seem to compile this code, and yet its supposed to because this is how our professor gave it to us on the website. Can anyone tell me what I need to make it compile? Thanks in advance.
ArrayList list = new ArrayList(5);
list.add(0, new Object());
list.add(new Object());
Object object = list.remove(1);
ArrayList<Player> players = new ArrayList<Player>(10);

public int compareTo(Player player) {
class PlayerNameComparator implements Comparator<Player> {
public int compare(Player player1, Player player2) {
class MyStack {
public int tos;
public Comparable list[];
// public ArrayList<Player> list;
public MyStack() {
    tos = 0;
    list = new Comparable[10];
public Comparable pop() {
    tos--;
    Comparable comparable = list[tos];
    list[tos] = null;
    return comparable;
public void push(Comparable element) {
    list[tos] = element;
    tos++;
public String toString() {
    String data = new String();
    MyStack temp = new MyStack();
    Comparable element = null;
    while (this.tos > 0) {
      element = this.pop();
      temp.push(element);
      data = data + element.toString();
    while (temp.tos > 0) {
      this.push(temp.pop());
}

The compiler always produces helpful messages which describe why text won't compile. If you can't understand them it would be a good idea to post those compiler messages.

I can't compile this, why?

I do not possess any means of compiling any .java file that imports javax.* or anything J2SE-related, thus, I have to compile it remotely on a remote host (www.myjavaserver.com), however, for some reason this file will not compile but will not produce any errors, warnings, or any display of any kind - but no .class file is ever found.

Sorry I can't do that, as much as I want to. My
computer is very ancient and has too little memory to
run any kind of server program, especially a
Java-related one. I tried with Eclipse a while back
(2 years ago and never figured it out, way too hard
in spite of my PC's inability to interact with it)
nearly destroyed my machine with it.You actually don't need to run any server. You just need to get the .JAR files (you should try to get the same server and version that you deploy on ... but that may not be possible). Then you put them in your Java Classpath, and you will be able to compile (from command line, or whatever). You could then un-install the server if you wanted to...
>
That means I can only compile J2SE formatted classes
remotelyThat would be J2EE. J2SE is the standard edition, where you get the compiler, java.lang.String, java.util.Date, and all the rest of the core stuff. J2EE is the enterprise edition for getting the javax.servlet packages (among others).
More comments on how you might change added as comments in the code...
on www.myjavaserver.com - provided it is
working.
I made the changes necessary and still can't compile
it!

How come I can't compile this file in this folder,but can in others

import java.util.*;

String s2 = (String)o2;

this code can be compiled in any folders except

why??? the error is:

It looks like you have a class called "Object" in that same directory that the compiler is using when you use "Object", and then the compiler complains because it wasn't "java.lang.Object". Get rid of it -- you should have called it something else, anyway.

Help! I can't compile this program

1:install Java SE,set the path variable to the directory of the bin folder(including bin).
2:download the JavaMail 1.4 release from http://java.sun.com/products/javamail/downloads/index.html
3:extract the downloaded file to any location and add the directory of its mail.jar file to classpath.
4:download the JavaBeans Activation Framework 1.1release from
http://java.sun.com/products/javabeans/jaf/downloads/index.html#download
5:extract the downloaded file to any location and add the directory of its activation.jar file to classpath.
then everything goes smoothly
You inspired me and voronetskyy told me exactly what to do,so thak both of you again!:-)

Can't Compile this!

Hi guys,
I am trying to establish development platform for my new website. I installed latest JDK and compiled small program which worked well. Then I installed Apache Tomcat and tried to do a small servlet test. This program is meant to display html test page saying "Hello world!":
public class ServletTest extends HttpServlet
          public void doGet(
               HttpServletRequest request,
               HttpServletResponse response)
           throws ServletException, IOException
           response.setContentType("text/html");
           PrintWriter out = response.getWriter();
           String docType =
                   "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
                   "Transitional//EN\">\n";
           out.println(docType +
                 "<HTML>\n" +
                "<HEAD><TITLE>Hello WWW</TITLE></HEAD>\n" +
                "<BODY>\n" +
                "<H1>Hello World - Servlet speaking</H1>\n" +
              "</BODY></HTML>");

My user/system environment classpath variable goes to: C:\Program Files\Java\jdk1.6.0_10\jre\lib
What can cause this problem?

Thanks for that...
I found and downloaded: servletapi2_1_1-win.zip file which should contain the classes and source files for the Java Servlet 2.1.1 javax.servlet and javax.servlet.http packages
Zipped folder contains:
api and src folders
in addition to that there are following files in zipped folder: license, readme, servlet.jar
I have extracted all of that into my C:\Program Files\Java\jdk1.6.0_10 folder and then copied servlet.jar into C:\Program Files\Java\jdk1.6.0_10\jre\lib folder
I tried to compile my ServletTest.jar but ther is still same error.
Have I done everything right?

Newbie can't compile this

Hi guys I'm a new Java programmer trying to learn this java thing. Anyway I have two classes in the same directory, class B compiles fine.
Class A have a problem reaching the B file why is this? Code follows.
/* B.java */
public class B
     B()
          System.out.println("Inside B constructor");
/* A.java */
public class A
     A()
          System.out.println("Inside A constructor");
     public static void main(String[] args)
          A a = new A();
          B b = new B();
When trying to compile A.java I get this error message.
cannot find symbol

_#1_ for a start you could call the method the right way,it's declared to accept an int parameter, you're calling it as a variable
_>>>>>>>>>declaration <<<<<<<<<<<_
private void PrintNumInEnglish(int num)_>>>>>>>call <<<<<<<<<<<_
System.out.println("\n" + PrintNumInEnglish + " bottles of beer on the wall");_#2_ your method is of type void that is returns nothing, while your call to the method expects a string back (or something else )
_#3_ your method is declared as an instance method and you're calling it in a static context, so either:
a- instatiate an object of type Rooker_Ch4_1 and call the method on it
Rooker_Ch4_1 var = new Rooker_Ch4_1();
var.PrintNumInEnglish(0);b- simply declare the method as static

Anyone can compile this program?Duke will be rewarded

Anyone can help me compile this program..I try debugging a lot of time but it is not working!

The program compiles over here. It just has some deprecation warnings ...or is that what you wanted debugged?
Don't use reshape() ...I think in AWT you should now use setBounds();
Don't use list.addItem(); ...looks like the API steers us to list.add();
Don't use Thread.resume() ...I don't think there is a replacement (unneccessary?).
Gee, this program must have ran the chat program in Ford's old model T ... !! (??)

Can someone else try to compile this and see why the program is returning..

Can someone else try to compile this and see why the program is returning "false" when I try to delete the files on exit (at bottom of code)... I have the source code uploaded to the web as well as my 2 text test files inside a zip file(they need to be unzipped so you can try to test the program) and .class file... the program works the way i want it to, but i just can't seem to delete the 3 temporary files i use... why??? why does it return false???

I tired your program, it still gives false for files deleted. I tool the same functions you used in your program and ran it. The files get deleted. Tried this :

public class FileTest {
     public static void main(String args[]) {
          FileTest f = new FileTest();
          try {
               f.createFile();
               f.deleteFile();
          } catch(IOException ioe){
               System.out.println(ioe.getMessage());
     public void createFile() throws IOException {
          System.out.println("In create file method...");
          File test = new File("test1.txt");
          File tst = new File("text2.txt");
          PrintStream testStream = new PrintStream (new FileOutputStream (test));
          PrintStream tstStream = new PrintStream (new FileOutputStream (tst));
          testStream.println("this is a test to delete a file");
          tstStream.println("this is the second file created");
          testStream.close();
          tstStream.close();
     public void deleteFile() throws IOException {
          File test = new File("test1.txt");
          File tst = new File("text2.txt");
          System.out.println(test.delete());
          System.out.println(tst.delete());
</pre>
Also check the starting and closing braces for your if..else blocks.

I can't compile any project...

Hello,
I installed Alchemy correctly, but when I try too compile my project, I always get this error message :
I don't understand why, since llvm-stub.exe is in the same folder as llvm-ld.
I'm using Alchemy with Cygwin btw.
Thanks in advance for you help

I'm not to familiar with fmod, but it would look like from the web page that it's a library (in windows it would be a dll I asume) that you can make calls to. If that's they case, Alchemy is not for you.
Alchemy does not do anything that you can't do in the FlashPlayer / Air runtimes.
Alchemy does not generate platform bytecode.
Alchemy does generate FlashPlayer bytecode.
Alchemy does not get arround the FlashPlayer sandbox.
Alchmey let's you port C/C++ code and turn it into FlashPlayer bytecodes.
If you have the sourcecode for fmod and you wish to compile the sourcecode, you can, but you will NOT have direct access to the hardware, that goes against the principle of Flash security sandbox.
That said... there are future things comming up, which I unfortunately can't disclose, that might help you with that plan in the near future, but it sounds like you have the wrong concept of what Alchemy is.
Whatever problem is that you are having, it's in your setup. There is no "magic", it works out of the box if you follow the steps properly, so if you did, then it might be something in your system that is causing the conflict.
As an observation:
if you get a "The file exists" error when you are creating the symbolic link, then that's probably your problem.
As stupid as this sounds, make absolutely 100% sure that you DID remove the llvm-stub.exe file before you create the symbolic link again, and make sure that you are in the right directory when you do so. You should NOT get "The file exists" error when creating the link.
BTW. that would have nothing to do with Alchemy, but more with cygwin.
You have no idea how many IT certified [InsertWhateverHere] experts have I told to check the basics, which they asure me they have, and when I go step by step, it turns out to be something basic.
Sometimes you are looking to blame something else, and miss the obvious.

When I download a CD to iTunes, some CD's appear as separate albums. How can I correct this?

When I download a CD to iTunes, some CD's appear as separate albums. How can I correct this?
for some reason iTunes appears to believe some tracts are from a separate album. For instance, one recently released Rod Stewart CD HAS 8 tracts on one album and the remaining two tracts on two separate albums, all albums are called the correct album name?

If your CD has tracks with different artists, or if there are differences in how the artist field is filled in for the different tracks, then you can fix this by identifying the disc as a 'compilation' CD.
Select all of the tracks in the CD, then 'get info' (control-I), and go to 'Options'. Select 'yes' for 'Part of a compilation'. That should fix the problem.
