learning java

[Michael Karl]

>hi,

I'm learning java. But when I compiled this code in the console 

import java.awt.*;
public class fenster extends Frame
{
  public static void main (String args[])
  {
fenster hauptfenster=new fenster();
hauptfenster.reSize (300,300);
hauptfenster.setLocation (100,100);
hauptfenster.setTitle ("Das Java Programm!");
hauptfenster.show();
  }
  public fenster()
  {
   Label ausgabe=new Label ("Hallo Linux-Welt!");
   ausgabe.setAlignment (Label.CENTER);
   add (ausgabe);
   }
}

I got this warning:

javac hallo.java
hallo.java:2: Public class fenster must be defined in a file called 
"fenster.java".
public class fenster extends Frame
 ^
1 error

But I don't know what this warning means. I controlled the code but it was the 
same which the code in the book. I hope you can help me with my problem

Mika
P.S. sorry for my bad english, I'm german

You seemed to have missed what the error says. just rename the file to
fenster.java. All public classes must be in a file with the same name. You
can add private ones to the file without changing the name though. Regards!
