The public type PlayerQuitListener must be defined in its own file

I am almost done with making a compass that tracks a player but Im getting this error "The public type PlayerQuitListener must be defined in its own file" so i made a new file called "PlayerQuitListener.java" but it is still not fixed? How would I fix this? Thank you!
Main Error
How I tried to fix it

Just rename the file in PlayerQuitListener.java and it should be fine,the problem is that the class name must match the file name, delete the empty file, rename CPCommand.java in PlayerQuitListener.java and it should work

Itext hyphenation in Table cells

I´m creating a table using iText.
But the output looks really bad, because of the hyphenation, which seems not to be done properly.
I allready read this question How to hyphenate text?
and this example http://itextpdf.com/sandbox/tables/HyphenationExample
I tried the example in eclipse after i added the itext_hyph_xml.jar to my class path. No error is thrown when i run the code, but the lines
Hyphenator h = new Hyphenator("de", "DE", 2, 2);
Hyphenation s = h.hyphenate("Leistungsscheinziffer");
System.out.println(s);
print null to the console instead of "Lei-stungs-schein-zif-fer" or something similar as i expected.
I tried playing with the parameters in
chunk.setHyphenation(new HyphenationAuto("de", "DE", 2,2));
but the output in the document never differes even slightly.
The code i´m trying to get to work looks kind of like this by the way:
for(String s: interest){
Chunk chunk = new Chunk(s,FONT[0]);
chunk.setHyphenation(new HyphenationAuto("de", "DE", 2,3));
table.addCell(new Phrase(chunk));
}

Ok I figured it out on my own now.
And because i couldn´t find the answer on the internet i thought i will share it here so anyone who might have the same error in the future wouldn´t need a week to figure it out.
It seems that in the class Hyphenator the defaultHyphLocation is set like this:
private static final String defaultHyphLocation = "com/itextpdf/text/pdf/hyphenation/hyph/";
But the structure of itext_hyph.jar looks like this:
com.lowagie.text.pdf.hyphenation.hyph
Obviously loading a hyph file from the jar will surely fail, since the path used by Hyphenator can not be found. I actually thought this would cause an error but it seems simply null is returned when the loading of the hyph file fails.
Calling Hyphenator.setHyphenDir("com/lowagie/text/pdf/hyphenation/hyph/"); however wouldn´t change a thing as one would think, since it changes the wrong string variable.
The only thing i could think of to solve this problem was to recreate the itext_hyph.jar according to the path given in Hyphenator and that acctually fixed it. Hyphenation is now working.

Java `Cannot Find Symbol`

I am getting an error in line: generateCsvFile("c:\\test.csv");:
I am trying to change my current program's output from a text field to csv file by following this.
I added the imports and then
I added the line generateCsvFile("c:\\test.csv"); to my main, and that is when I got this error... Why so?
Note: I am a beginner

You need to declare and define either a static function using private static void generateCSVFile(String fileName) or a function public void generateCSVFile(String fileName)in some class ABC and call it using ObjectofClassABC.generateCSVFile(string fileName)

See that the line generateCsvFile("c:\test.csv"); is calling a function named generateCsvFile which is not a predefined function, so you will need to make a function named that. And if you see the tutorial, after that line the function generateCsvFile() is defined so unless you define it you cannot call it and that's why it is giving error. Once you add that part your error will go away.

Android programming ,Syntax error on token "Invalid Character", delete this token

i am beginner in android programming . i tried to add a text view or anything in my app. but
somehow in id class which is automatically generated in r.java , i am getting invalid character as u can see in textview and i can't delete it or alter it . need help!!!!!!!!!!!!!!!!!
public static final class id {
public static final int action_settings=0x7f080001;
public static final int textView१=0x7f080000;
}
Syntax error on token "Invalid Character", delete this token

You can see it yourself. This:
textView१
Is not an acceptable name.
This one is:
textView1
This one also is:
txtSomething
Delete R.java and change the name in your xml layout.
Yes, you can

§ character is not allowed in variable names, simply remove it from your variable textView१ to correct the error.
The generated code file may be read-only, so change the file property to make it editable. If you don't have the source file, then you may try to edit the class file using classeditor

Give it a try:
1. Delete R.java
2. uncheck Preferences->General->Startup and Shutdown->Android Development Toolkit
3. check it back and restart eclipse, then R will generate automatically

I had an error saying that I had an invalid token on my R.java and indeed a string had an ' at the variable name, which is not permitted of course, but that string was not made by me but by the system so i could not fix it manually !
What I did was cleaning and building not only the current project but also the support library that I used for that project. Doing so the error popped up on the library project also !
Since I could not fix it manually, I deleted the support library and reimported a new support library which solved my problem.

R.java strange error

I cannot figure out which kind of error is this.
We all saw a lot of strange stuff, regarding android and R.java, but I am seeing this for the first time.
In the R.java, i have the following line of code:
public static final class id {
public static final int 15dp=0x7f060067;
The error says - Syntax error on token "15d". delete this token.
At first I thought that I made some typo and wrote "15d" instead of "15dp" somewhere, but I didn't. I checked the entire layout xml file, that I was making the last, since after making it this error started appearing.
I tried deleting R.java and building the app, didn't helped.
Does anybody has a clue what this might be ?

You probably have in some layout file something like this:
android:id="+#id/15dp"
change this to a vaild id and try it again.

i know this question is already answered,but some more knowledge about this error:
R.java maintains all the references of id's of views,strings.xml tag names,Drawables etc, if you are facing this kind of issue,then it is necessarily the error of miss spell in some id naming,sting tag names or drawable name's something like this:
android:id="+#id/15dp"
dp is the unit for density independent pixel,so we can not assign this as id to any view neither as drawable name nor string tag name.
hope this helps.
