Can we use static method in an abstract class?

Solution 1:

In Java you can have a static method in an abstract class:

abstract class Foo {
   static void bar() { }
}

This is allowed because that method can be called directly, even if you do not have an instance of the abstract class:

Foo.bar();

However, for the same reason, you can't declare a static method to be abstract. Normally, the compiler can guarantee that an abstract method will have a real implementation any time that it is called, because you can't create an instance of an abstract class. But since a static method can be called directly, making it abstract would make it possible to call an undefined method.

abstract class Foo {
   abstract static void bar();
}

// Calling a method with no body!
Foo.bar();

In an interface, all methods are implicitly abstract. This is why an interface cannot declare a static method. (There's no architectural reason why an interface couldn't have a static method, but I suspect the writers of the JLS felt that that would encourage misuse of interfaces)

Solution 2:

If you are talking about java, answer is Yes But you need to define the static method. You cannot create an abstract static method. What you can create is non abstract static method.

Reason is you do not need a object instance to access a static method, so you need the method to be defined with a certain functionality.

so you cannot have,

  abstract class AbstractClassExample{
     abstract static void method();


}  

But you can have,

abstract class AbstractClassExample{

     static void method(){}
}  

Hope this helps...

Solution 3:

Here is a simple explanation.Abstract methods must be implemented later.We know that static methods cannot be overridden because static methods do not belong to any particular instance, rather it belongs to the class.Then different implementation of abstract method,which is static, in different classes is counter-intuitive.
