In your example, there is no subclassing going on.... but yea, you are not allowed to define a non-static non-private method in the subclass, with the same name and signature, as a static method in the super class.

In Java, many times you are allowed to do things that 'look wrong' but because they don't completely violate a rule, they're allowed to happen. This is one of those cases where you'd think you'd be able to bend the rules a bit and get away with it. But in fact, if you try and have a named method with the same name as a static method in the parent, you get slapped on the wrist by Java.

Indeed, this isn't overriding by definition. It's still wrong though.

And static methods cannot be overridden. Refer this

subclass has no access to superclass's static method. so, why there is restriction to define same method name as non-static
and if i define same method name with static in subclass it is compiling properly
