i know that we cannot override static methods in java. I read here why:

but can someone explain the following code:

    class A
    {
        public static void a()
        {
            System.out.println("A.a()");
        }
    }  
 
    class B extends A
    {
        public static void a()
        {
            System.out.println("B.a()");
        }
    }

how was I able to override function a() in class B? why did it work here or am I missing something.

    Re: Example of Overrinding static method in java

    you didn't override anything here. To see for yourself, Try putting @Override annotation before public static void a() in class B and Java will throw an error.

    You just defined a function in class B called a(), which is distinct (no relation whatsoever) from the function a() in class A.

    But Because B.a() has the same name as a function in the parent class, it hides A.a() [As pointed by Eng. Fouad]. At runtime, the compiler uses the actual class of the declared reference to determine which method to run. For example,
    B b = new B();
           b.a();
           A a = (A)b;
           a.a()

    You cannot override static methods in Java. Remember static methods and fields are associated with the class, not with the objects. (Although, in some languages like Smalltalk, this is possible).
