What is static in java?
Static means one per class, not one for each object no matter how many example of a class might exist. This means that you can use them without making an instance of a class.Static methods are implicitly final, because overriding is done based on the type of the object, and static methods are attached to a class, not an object.
A static method in a super class can be shadowed by another static method in a subclass, as long as the unique method was not declared final. Though, you can't override a static method with a nonstatic method. In other words, you can't alter a static method into an instance method in a subclass.
