The game of statics

I read on all the forums so many times that Static methods cannot be inherited and cannot be overridden. But I came across the code which is allowing me to override and inherit static methods. Please go through the code below for overriding the static method.


package foo;

class A{

A(){
System.out.println("Here is A's constructor");
}

public static void print()
{
System.out.println("Printing A");
}

}

public class B extends A{

B(){
System.out.println("Here is B's constructor");
}

public static void print()
{
System.out.println("Printing B");
}


public static void main(String[] args){

B b = new B();

B.print();

A.print();

}
}

The output I got for this was allowing me to override this method print. It worked fine. Please let me know if it is really possible to override and inherit static method.

Hi Harshad,

Whar do you mean by inheritance ?

try this :
A a = new B();
a.print();
you will know it by yourself !


Thanks & Regards, T.Srinivasan

That example doesn't demonstrate overriding.

Static methods can be inherited by subclasses.

However, you cannot override them.

Hi Keith,

I just want Harsad to know the fact that "overriding will not take place by that code."

You got me wrong. So sad.

Sorry Srinivasan. My post was a comment to the OP, not a criticism of your post.

Harshaut Raut, welcome to the Ranch.

try this :
A a = new B();
a.print();
Now try thisYou have two separate methods in different classes, which just happen to have the same name.

Try this:-Result: won't work. You are not overriding at all.
 
I agree. Here's the link: http://aspose.com/file-tools
