Problem with out variable
I have been working for months with java and all of a sudden today when i was compiling a program i got an error stating that the variable out can't be.
To confirm my suspicion that somrhtings wrong i wrote this program and tested it
class Example
{
publicstaticvoid main(String args[])
{
System.out.println("This is my first program");
}
}
And i get this error when i compile
Cannot find symbol
variable out
All this time the JRE was ok and now this unexpected problem.Whats happening?It works if I import java.lang.System and run the program.I have been working for months and this is the first time.Is it because of some virus or something.Should i reinstall the JDK.I thought of asking at the forum before i could try reinstalling and checking it out again.

Hi,Looks like a problem with your installation of the JDK / JRE, or that something has changed the registry or environment variables. The easiest thing is probably to re-install the JDK / JRE.Kaj
.. Where do you get this error? Eclipse has a bug which is related to this. Sometimes I have to remove the JRE from installed JREs in Eclipse, and then just add it again, and then everything works.Kaj

I don't use an IDE.I use the command prompt.I get the error at the command prompt.
My computer has two OS both XP.I jdk 1.5 installed on both these OS.I run the jdk on the first jdk which is on the active partition and when it stopped working on this one i immediately restarted the pc and started the other xp where i have installed jdk 1.5 too.But even there it's the same case.
But if any environment variables or registry contents have changed thats local to the first xp but how will it effect the second xp.Is it because of any virus
Please note i will be going out and will get back to the thread in around 2 hours.Thanks a lot of the response.

It's probably not related to a virus. My guess is that you have installed some application and that caused a conflict.

It's almost 6 months since i installed the jdk and working with it.So it can't be the problem witha ny installation.

Absolutely none.I haven't installed any on the first OS.I installed a ipod veideo converter on the second OS but thats in no way related to the first OS.The only thing i did was download a few ebooks around 3 hours ago and the problem started then.

My guess is you have a class named System that perhaps you created or the ebooks created.The compiler is finding this class instead of java.lang.System.
Could you please post :all of your test class code (including imports), the exact command you use when compiling andthe version of the VM you use (java.exe -version)

It's the same code i posted at the top.Just a simple System.out.println( ) inside the main method.
Here it is again
class example
{
public static void main(String args[])
{
System.out.println("This is my first program");
}
}
I haven.t imported as java.lang package is imported by default.It was working all this time and now all of a sudden it's started behaving like this today.What beats me is that even the jdk 1.5 installed on the second xp in the other drive is also behaving the same way too.
Did you read reply #7?
To test this theory out, do this instead (temporarily):
java.lang.System.out.println("This is my first program");
If that works, then the conclusion would be that you do have a homemade class named "System" in your classpath at compile-time.

I did read reply 7.There wasn't a class named System which i created in my classpath.Now however i have reinstalled the jdk and it's working fine.
