static : Bug in K&B P-145

[Sandeep Vaid]

At Page 145 (K& B book)

So, the way we access a static method (or static variable) is to use the dot operator on the class name, as opposed to using it on a reference to an instance.

public class Static_Access {
 
 static int i;
int j;
   public static void main(String args[])
   {
System.out.println("i=" + i);
System.out.println("Temp1.i=" + Static_Access.i);
System.out.println("new Temp1().i = " + new Static_Access().i);

Static_Access s = new Static_Access();
System.out.println("s.j=" + s.j);



   }
}

static members can be accessed by the [instanse_name.static_member].

Neither compiler nor JVM complains about this.
But the resul remains same whether one use class name or instanse name.

[Matt Russell]

At the bottom of that page, K&B say, "the Java language also allows you to use an object reference to access a static member".

Hi cowboys,

this isn't a bug. One sentence before, it is said that

But this approach (using a reference to an object) isn't appropriate for accessing a static method, (...)
