What are class methods in different programming languages?

Can you explain what class methods are in Python?

In Python, class methods are methods that are bound to the class rather than its instance. They are defined using the @classmethod decorator and take 'cls' as the first parameter.

How do class methods differ in Java?

In Java, class methods are called static methods. They are defined using the 'static' keyword and can be called without creating an instance of the class.

What about in Ruby?

In Ruby, class methods are defined with 'self.' before the method name. They can be called on the class itself, not on instances.

Are there any languages that don't support class methods?

Yes, some languages like C do not have built-in support for class methods as they are not object-oriented. However, similar functionality can be achieved through other means.
