RE: [OT] Use of Static Methods

[Micael]

This use of "overriding" is mistaken.  It is the wrong technical term. You 
can tell it does not override by building a driver and seeing results with 
the wrongly called "overridden" method.  You will run the method from the 
parent class if you use a wrongly called overridden static method "static 
String do()" in the child class.

Thus,

Parent instance1 = new Child();
instance1.do();
will return the results of the Parent implementation of do() and

Child instance2 = new Child();
instance2.do();
will return the results of the Child implemenation of do(), so, and this is 
NOT MERE SEMANTICS, the child static method DOES NOT OVERRIDE the parent 
method.

Perhaps everyone is correct here. Technically, as Brian showed, the language
does not prevent you from overriding a method signature in a subclass,
however, behaviorally, it will not completely behave like an overridden
method. Like I pointed out in a previous email, you will not get polymorphic
behavior with the method. As Kris pointed out it is hiding the behavior of
the parent class.
I hope this satisfies everyone's points on this topic now.

Actually, that's incorrect. Static method can be overridden.

foo.java
public class foo{
public static void bar(){}
}
baz.java
public class baz extends foo{
public static void bar(){}
}
compiles
