inquisition question

public class pack
{
   static public int x1 = 7;
   static protected int x2 = 8;
   static int x3=9;
   static private int x4 =10;
}

import packed.pack;
class test extends pack
{
   public static void main( String args[] )
   {
      pack p = new pack();
      System.out.println( pack.x2 );
   }
}    

i think this doesnt compile....but the exam says that the answer is 8 since x2is static.....how? what does static has to do with this?

We can access static member using ClassName,
In your example we cam access x2 using pack, since x2 is a static variable.

oh ya....since it is static it is being inherited.....never looked that way before

Actually, it has nothing to do whether it is static or not.

In your example, you can access x2 because you class extends Pack. The static member x2 in Pack is protected, which means classes extending this one have access to it.

The previous post simply implied that you do not need an instance of Pack to get access to x2, because x2 is a static member. Therefore, you could simply right Pack.x2 to gain access to it.
