Javac generating Wierd error during compilation

Question

Hello friends
I am reading Kathy Sierra and I wish to give SCJP exam.
Today when I tried to test the concept of protected V/S Default access modifier I got struck with a problem.
Below is the code:
package xyz;
class ProtTestParent
     protected int x=10;
public class ProtTestChild extends ProtTestParent
     public static void main(String[] ar)
          new ProtTestChild().get();
     public void get()
          System.out.println("Value of x "+x);
If I try to compile it I get following error:
C:\Program Files\Java\jdk1.5.0_06\bin>javac ProtTestChild.java error: cannot read: ProtTestChild.java 1 error C:\Program Files\Java\jdk1.5.0_06\bin>
Can anyone tell me what could be the problem??
Thanks

Please use code tags around your posted code, it makes it much easier to read.
I see a couple of issues.
First, you are calling javac from the binary directory it is in - is that also where you put your code? If your code is in java's \bin directory - that's generally bad practice.
If java is correctly installed, you should be able to call javac from anywhere, because the java \bin directory will be in your path.
Also, the ProtTestChild code indicates that it is in package xyz - so the file has to be in a directory named xyz, and you have to call the compiler from the directory that contains this xyz directory. So, for example, if the java file is in C:\myJavaCode\xyz, you need to be in C:\myJavaCode, and type the command "javac xyz\ProtChildTest.java".
Try that, see if it works. I don't use the command line much anymore, so I could be wrong.
